Introduction
Hardware Monitoring Overview
Hardware Monitoring Overview
What is Hardware Monitoring?
Hardware monitoring is the process of watching a hardware resource (such as a disk) for the occurrence of
any unusual activity, called an event. When an event occurs, it is reported using a variety of notification
methods (such as email). Event detection and notification are all handled automatically with minimal
involvement on your part.
To achieve a high level of system reliability and availability, it is essential that you know when any system
resource is experiencing a problem. Hardware monitoring gives you the ability to detect problems with your
system hardware resources. By providing immediate detection and notification, hardware monitoring allows
you to quickly identify and correct problems—often before they impact system operation.
Another important feature of hardware monitoring is its integration with applications responsible for
maintaining system availability, such as MC/ServiceGuard. It is vital that these applications be alerted to
hardware problems immediately so they can take the necessary action to avoid system interruption.
Hardware monitoring is easily integrated with MC/ServiceGuard, and the necessary notification methods are
provided for communication with other applications such as HP OpenView.
Hardware monitoring is designed to provide a high level of protection against system hardware failure with
minimal impact on system performance. By using hardware monitoring, you can virtually eliminate
undetected hardware failures that could interrupt system operation or cause data loss.

Introduction
Hardware Monitoring Overview
How Does Hardware Monitoring Work?
The following figure shows the basic components involved in hardware monitoring.
Figure 1-1
Components Involved in Hardware Monitoring
The typical hardware monitoring process works as follows:
1. While monitoring its hardware resources, the hardware event monitor detects some type of abnormal
behavior on one of the resources.
2. The hardware event monitor creates the appropriate event message, which includes suggested corrective
action, and passes it to the Event Monitoring Service (EMS).
3. EMS sends the event message to the system administrator using the notification method specified in the
monitoring request.
4. The system administrator (or Hewlett-Packard service provider) receives the messages, corrects the
problem, and returns the hardware to its normal operating condition.
5. If the PSM has been properly configured, events are also processed by the PSM. The PSM changes the
device status to DOWN if the event is serious enough. The change in device status is passed to EMS,
which in turn alerts MC/ServiceGuard. The DOWN status will cause MC/ServiceGuard to failover any
package associated with the failed hardware resource.
NOTE
The Difference Between Hardware Event Monitoring and Hardware Status
Monitoring
Hardware event monitoring is the detection of events experienced by a hardware resource. It is
the task of the EMS Hardware Monitors to detect hardware events. Events are temporary in
the sense that the monitor detects them but does not remember them. Of course the event itself
may not be temporary—a failed disk will likely remain failed until it is replaced.
Hardware status monitoring is an extension of event monitoring that converts an event to a
change in device status. This conversion, performed by the PSM, provides a mechanism for
remembering the occurrence of an event by storing the resultant status. This persistence
provides compatibility with applications such as MC/ServiceGuard, which require a change in
device status to manage high availability packages.

Hardware Monitoring Overview
Benefits of Hardware Monitoring
Hardware monitoring provides the following benefits:
•
•
•
•
Reduces system downtime by detecting hardware failures when they occur, allowing you to quickly
identify and correct problems.
Integrates with MC/ServiceGuard and other applications responsible for maintaining system availability.
These applications can now add many hardware resources to the components they monitor.
Minimizes the time required to isolate and repair failures through detailed messages describing what the
problem is and how to fix it.
Includes a default monitoring configuration that offers immediate protection for your system hardware
without any intervention on your part after monitoring is enabled.
•
•
Provides a common tool for monitoring a wide variety of system hardware resources.
Offers a variety of notification methods to alert you when a problem occurs. You no longer need to check
the system console to determine if something has gone wrong.
•
Requires minimal maintenance once installed and configured. New hardware resources added to the
system are automatically included in the monitoring structure.

Introduction
Hardware Monitoring Overview
Tips for Hardware Monitoring
Here are some tips for using hardware monitoring.
ꢀ
Keep hardware monitoring enabled to protect your system from undetected failures. Hardware
monitoring is an important tool for maintaining high-availability on your system. In a high-availability
environment, the failure of a hardware resource makes the system vulnerable to another failure. Until
the failed hardware is repaired, the backup hardware resource represents a single-point of failure.
Without hardware monitoring you may not be aware of the failure. But if you are using hardware
monitoring, you are alerted to the failure. This allows you to repair the failure and restore
high-availability as quickly as possible.
ꢀ
Integrate the PSM into your MC/ServiceGuard strategy. An important feature of hardware
monitoring is its ability to communicate with applications responsible for maintaining system
availability, such as MC/ServiceGuard. The PSM allows you to integrate hardware monitoring into
MC/ServiceGuard. The PSM gives you the ability to failover a package based on an event detected by
hardware monitoring. If you are using MC/ServiceGuard, you should consider using the PSM to include
your system hardware resources in the MC/ServiceGuard strategy. In addition, the necessary notification
methods are provided for communicating with network management application such as HP OpenView.
ꢀ
ꢀ
Utilize the many notification methods available. The notification methods provided by hardware
monitoring provide a great deal of flexibility in designing a strategy to keep you informed of how well your
system hardware is working. The default monitoring configuration was selected to provide a variety of
notification for all supported hardware resources. As you become familiar with hardware monitoring, you
may want to customize the monitoring to meet your individual requirements.
Use e-mail and/or text file notification methods for all your requests. Both of these methods,
which are included in the default monitoring, receive the entire content of the message so you can read it
immediately. Methods such as console and syslog alert you to the occurrence of an event but do not deliver
the entire message. You are required to retrieve the message using the resdatautility, which requires an
additional step.
ꢀ
ꢀ
Use the `All monitors' option when creating a monitoring request. This option enables monitoring
request to all monitors. It ensures any new class of hardware resource added to your system is
automatically monitored. This means that new hardware is protected from undetected hardware failure
with no effort on your part.
Easily replicate your hardware monitoring on all your systems. Once you have implemented a
hardware monitoring strategy on one of your systems, you can replicate that same monitoring on other
systems. Simply copy all of the hardware monitor configuration files to each system that will use the same
monitoring. The monitor configuration files are found at /var/stm/config/tools/monitor. Of course,
you must have installed hardware event monitoring on each system before you copy the configuration files
to it. Be sure to enable monitoring on all systems.

Introduction
Hardware Monitoring Overview
Hardware Monitoring Terms
The following terms are used throughout this guide. Understanding them is important when learning how
the hardware event monitors work and how to use them effectively.
Table 1-1
Hardware Monitoring Terms
Term
Definition
Asynchronous event
detection
The ability to detect an event at the time it occurs. When an
event occurs the monitor is immediately aware of it. This
method provides quicker notification response than polling.
Default monitoring
request
The default monitoring configuration created when the EMS
Hardware Monitors are installed. The default requests
ensure that a complete level of protection is automatically
provided for all supported hardware resources.
Event Monitoring
Service (EMS)
The application framework used for monitoring system
resources on HP-UX 10.20 and 11.x. EMS Hardware
Monitors use the EMS framework for reporting events and
creating PSM monitoring requests. The EMS framework is
also used by EMS High Availability Monitors.
EMS Hardware
Monitors
The monitors described in this manual. They monitor
hardware resources such as I/O devices (disk arrays, tape
drives, etc.), interface cards, and memory. They are
distributed on the Support Plus Media and are managed
with the Hardware Monitoring Request Manager
(monconfig).
EMS High
Availability (HA)
Monitors
These monitors are different from EMS Hardware Monitors
and are not described in this manual. They monitor disk
resources, cluster resources, network resources and system
resources. They are designed for a high availability
environment and are available at additional cost. For more
information, refer to Using EMS HA Monitors, which is
available at http://docs.hp.com/en/ha.html.
Event severity level
Each event that occurs within the hardware is assigned a
severity level, which reflects the impact the event may have
on system operation. The severity levels provide the
mechanism for directing event notification. For example, you
may choose a notification method for critical events that will
alert you immediately to their occurrence, and direct less
important events to a log file for examination at your
convenience. Also, when used with MC/ServiceGuard to
determine failover criteria, severe and critical events cause
failover.
Hardware event
Any unusual or notable activity experienced by a hardware
resource. For example, a disk drive that is not responding, or
a tape drive that does not have a tape loaded. When any such
activity occurs, the occurrence is reported as an event to the
event monitor.
21
Chapter 1
Introduction
Hardware Monitoring Overview
Table 1-1
Hardware Monitoring Terms (Continued)
Term
Definition
Hardware event
monitor
A monitor daemon that gathers information on the
operational status of hardware resources. Each monitor is
responsible for watching a specific group or type of hardware
resources. For example, the tape monitor handles all tape
devices on the system. The monitor may use polling or
asynchronous event detection for tracking events.
Unlike a status monitor, an event monitor does not
“remember” the occurrence of an event. It simply detects and
reports the event. An event can be converted into a more
permanent status condition using the PSM.
Hardware resource
MC/ServiceGuard
A hardware device used in system operation. Resources
supported by hardware monitoring include mass storage
devices such as disks and tapes, connectivity devices such as
hubs and multiplexors, and device adapters.
Hewlett-Packard's application for creating and managing
High Availability clusters of HP 9000 Series 800 computers.
A High Availability computer system allows application
services to continue in spite of a hardware or software
failure. Hardware monitoring integrates with
MC/ServiceGuard to ensure that hardware problems are
detected and reported immediately, allowing
MC/ServiceGuard to take the necessary action to maintain
system availability. MC/ServiceGuard is available at
additional cost
Monitoring request
A group of settings that define how events for a specific
monitor are handled by EMS. A monitoring request identifies
the severity levels of interest and the type of notification
method to use when an event occurs. A monitoring request is
applied to each hardware device (or instance) supported by
the monitor.
Monitoring requests are created for hardware events using
the Hardware Monitoring Request Manager. Monitoring
requests are created for changes in hardware status using
the EMS GUI.
Multiple-view
As of the HP-UX 11.00/10.20 June 2000 release (IPR 0006),
certain monitors will allow event reporting to be tailored for
different targets (clients). This “multiple-view”
(“Predictive-enabled”) feature will be added to all hardware
monitors in future releases. Previously, hardware monitors
generated events the same way for all targets. The problem
is that different targets, such as HP Support Applications,
may have different requirements for events.

Peripheral Status
Monitor (PSM)
Included with the hardware event monitors, the PSM is a
monitor daemon that acts as a hardware status monitor by
converting events to changes in hardware resource status.
This provides compatibility with MC/ServiceGuard, which
uses changes in status to manage cluster resources. Through
the EMS GUI, the PSM is also used to create hardware
status monitoring requests.
Polling
The process of connecting to a hardware resource at regular
intervals to determine its status. Any events that occur
between polling intervals will not be detected until the next
poll, unless the monitor supports asynchronous event
monitoring.
Predictive-enabled
Resource instance
See “multiple-view.” This feature enables hardware monitors
to work with HP Support Applications.
A specific hardware device. The resource instance is the last
element of the resource path and is typically the hardware
path to the resource (e.g., 10_12_5.0.0), but it may also be a
product ID as in the case of AutoRAID disk arrays. There
may be multiple instances for a monitor, each one
representing a unique hardware device for which the
monitor is responsible.
Resource path
Hardware event monitors are organized into classes (and
subclasses) for creating monitoring requests. These classes
identify the unique path to each hardware resource
supported by the monitor. Two similar resource paths exist
for each hardware resource—an event path used for creating
event monitoring requests, and a status path used for
creating PSM monitoring requests.

The Steps Involved
The Steps Involved
The steps involved in installing and configuring hardware monitoring are shown in Figure 2-1 on page 27.
Each step is described in detail in this chapter on the page indicated. Installation of Support Tools is
necessary if you have Diagnostic/IPR Media release earlier than the June 1999 release only. With HP-UX 11i,
the Support Tools are automatically installed when the OS is installed.
Step 1: Install the Support Tools from the most current copy of Support Plus Media you can find. You can
also download this package over the Web. See “Installing EMS Hardware Monitors”. This step is
necessary if you have Diagnostic/IPR Media release earlier than the June 1999 release only.
Step 2: Examine the list of supported products to see if any of your devices has special requirements in
order to be monitored. For example, if monitoring FC-AL hubs, edit the file:
/var/stm/config/tools/monitor/dm_fc_hub. See “Fibre Channel Arbitrated Loop Hub Monitor”.
Step 3: Enable hardware event monitoring. See “Enabling Hardware Event Monitoring”. This step is
necessary if you have Diagnostic/IPR Media release earlier than the June 1999 release only.
Step 4: Determine whether default monitoring requests are adequate. See “Viewing Current Monitoring
Requests”.
Step 5: Add or modify monitoring requests as necessary. See “Adding a Monitoring Request” and
“Modifying Monitoring Requests”.
Step 6: If desired, verify monitor operation (recommended, but optional). See “Verifying Hardware Event
Monitoring”.
NOTE
How Long Will it Take to Get Hardware Monitoring Working? (For Diagnostic/IPR
Media released earlier than the June 1999 release only.)
You can get hardware monitoring installed and working in minutes. Once the software is
installed, you simply need to run the Hardware Monitoring Request Manager and enable
monitoring. The default hardware monitoring configuration should meet your monitoring
requirements without any changes or modifications. If you find that the default monitoring
should be customized, you can always return later and add or modify monitoring requests as
needed.
NOTE
If I'm Already Using EMS HA Monitors, Can I Also Use the EMS GUI to Manage
Hardware Monitoring?
For the most part, no. Hardware event monitoring is managed using the Hardware Monitoring
Request Manager, which serves the same function the EMS GUI serves for the EMS HA
monitors. The only portion of hardware monitoring that is managed using the EMS GUI is
status monitoring done using the PSM described in Chapter 4, “Using the Peripheral Status

Installing EMS Hardware Monitors
Installing EMS Hardware Monitors
The EMS Hardware Monitors software is distributed with the Support Tools (diagnostics). All the necessary
files for hardware monitoring are installed automatically when the Support Tools are installed. There are
several different ways that the Support Tools are installed:
•
•
The Support Plus Media: installing the OnlineDiag depot from the Support Plus Media using swinstall.
HP Software Depot website: downloading the “Support Tools for the HP 9000” in the “Enhancement
Releases” product category, then using swinstallto install the OnlineDiag depot.
•
Automatic: with HP-UX 11i, the Support Tools are automatically installed from the OE CD-ROM when
the operating system is installed.
Complete instructions for installing STM are contained in Chapter 5 of the Support Plus: Diagnostics User's
Guide.
The following software components are installed for hardware monitoring:
•
•
•
•
All hardware event monitors
Monitor configuration files
Monitoring Request Manager
EMS framework, including the EMS graphical interface
All EMS Hardware Monitors on the CD-ROM will be installed on your system, but only those that support
hardware resources you are using will be active. If you add a new hardware resource to your system that uses
an installed monitor, the monitor will be launched when the system is restarted or following the execution of
the IOSCAN utility (which performs a real/hard ioscan).
NOTE
Reinstalling or upgrading the STM software will erase the current PSM configuration. Any
MC/ServiceGuard package dependencies or EMS monitoring requests you have created with
the PSM will be lost. Before reinstalling the STM software, record the current PSM
configuration so you can easily recreate it after the software has been installed. Or you can
comment out the PSM dependencies in the ServiceGuard configuration files, then re-enable
them after the STM software has been installed.
IOSCAN Utility
When you execute the IOSCAN utility, a “real/hard” ioscan is performed. The utility performs a scan of your
system hardware, gathering the most-current information.
Conversely, ‘ioscan -k’ is used by hardware monitors and diagnostics to obtain their information about
configured devices. The data returned by ‘ioscan -k’ is only as accurate as the last system reboot, or when a
“real/hard” ioscan is executed. This means that if a device or component is added to / removed from the
system, a “real/hard” ioscan should be executed in order to ensure an updated IOSCAN table in the kernel for
use by the hardware monitors and diagnostics. Otherwise, the hardware monitors and diagnostics will
operate on a stale, inaccurate picture of the system’s configuration.
Supported System Configuration
To use the hardware event monitors, your system must meet the following requirements:

Installing and Using Monitors
Using Hardware Monitoring Requests
Using Hardware Monitoring Requests
Monitoring requests are used to implement your strategy for monitoring hardware resources. The Hardware
Monitoring Request Manager is the tool you use to create and manage hardware event monitoring requests.
The following procedures describe how to use the Hardware Monitoring Request Manager to perform the
tasks involved in managing monitoring requests for all hardware event monitors.
What Is a Monitoring Request?
A monitoring request is the mechanism by which you manage how hardware event notification takes place.
EMS uses a monitoring request to determine what events should be reported, and what notification method
should be used to report them.
In building a monitoring request, you define the components that comprise the monitoring request. See
Figure 2-2 on page 40.
When building a request you must make the following decisions:
•
•
WHAT hardware should be monitored? This is defined by selecting the monitor responsible for the
hardware resources you want to monitor. You can select multiple monitors for each monitoring request,
which gives you the ability to use a single request for a variety of hardware.
WHAT events should be reported? Although the monitor can detect all hardware events, you can limit
the events that are reported. This is done by specifying the severity level(s) and an arithmetic operator.
Each severity level is assigned a numeric value to work with the operator (e.g., CRITICAL=5). Together
these settings determine which events to report. For example, you may be interested in all events greater
than or equal to Major Warning (>=MAJOR WARNING).
•
HOW will notification be sent? You must select the notification method you want to use when an event
occurs. You may want to use several notification methods, but each method will require its own
monitoring request.
Some Monitoring Request Examples
The following monitoring request applies to all monitors. It sends all events with a severity greater than or
equal to MAJOR WARNING to an email address of sysad@hp.com:
Send events generated by all monitors
with severity >= MAJOR WARNING to EMAIL sysad@hp.com
The following monitoring request sends information events for all monitors to a text log:
Send events generated by all monitors
with severity = INFORMATION to TEXTLOG /var/opt/resmon/log/information.log

Installing and Using Monitors
Enabling Hardware Event Monitoring
Enabling Hardware Event Monitoring
Hardware event monitoring must be enabled to protect your system from undetected hardware failures. All
hardware monitoring requests are ignored while monitoring is disabled. Once monitoring has been enabled,
all hardware event monitors and their associated monitoring requests will become operational.
NOTE
NOTE
As of the June 1999 release, the hardware event monitors are automatically enabled when the
Support Tools bundle containing STM and the monitors is installed.
Are There Any Fibre Channel Arbitrated Loop Hubs or Fibre Channel Switches You
Want to Monitor?
An EMS Hardware Monitor is included for FC-AL hubs and FC switches. However, unlike the
other hardware monitors, these monitors require some initial configuration before they will
function. To ensure that your FC-AL hubs or FC switches are monitored, you should perform
the initial configuration before enabling monitoring. For information on performing the initial
configuration, refer to “Fibre Channel Arbitrated Loop Hub Monitor”, and “Fibre Channel
return here and continue with the procedure to enable monitoring.
To enable hardware event monitoring (only necessary for February and April 1999 releases):
1. Run the Hardware Monitoring Request Manager by typing:
/etc/opt/resmon/lbin/monconfig
2. From the main menu selection prompt, enter E
Hardware event monitoring is now enabled. The default monitoring requests shown in Table 2-13 on page 43
will be used to monitor your hardware. If these settings are adequate, you are done. If you want to add or
modify the monitoring you can do so using the Monitoring Request Manager.

Chapter 2
Installing and Using Monitors
Enabling Hardware Event Monitoring
Default Monitoring Requests
A set of default monitoring requests are created for each hardware event monitor. These default requests
provide a complete level of monitoring and protection for the hardware resources under the control of the
monitor. The default monitoring requests listed in Table 2-13 on page 43 are used for all hardware event
monitors.
NOTE
When to Modify the Default Monitoring Requests
You can use the default monitoring requests provided and achieve a complete level of
protection. However, the default monitoring requests provide a limited number of notification
options. By modifying or adding new monitoring requests, you gain greater control over what
notification methods are used to alert you when events occur. You can add new notification
methods or remove those that may not be required. Creating custom monitoring requests also
allows you to manage which severity levels you want reported.

Listing Monitor Descriptions
One of the first steps in managing monitoring requests is selecting the proper monitor for the hardware
resource. You must know what hardware resources each monitor is responsible for to ensure that you select
the proper monitor. Listing the descriptions of the available monitors will show you what hardware resources
each monitor supports.
To list the descriptions of available monitors:
1. Run the Hardware Monitoring Request Manager by entering:
/etc/opt/resmon/lbin/monconfig
2. From the main menu selection prompt, enter L
A complete list of the available monitors and the hardware type each monitor supports is displayed. Identify
the name of the desired monitor and then proceed with the monitoring request task.
NOTE
For a detailed list of the specific products each monitor supports, refer to the Diagnostics

Chapter 2
Installing and Using Monitors
Adding a Monitoring Request
Adding a Monitoring Request
Adding a monitoring request is a convenient way to add another notification method for a monitor. Each new
notification method requires its own monitoring request.
Monitoring requests can only be added at the monitor level, which creates an identical request for all
instances of the hardware resources supported by the monitor. Monitoring requests cannot be added for a
specific hardware instance. An “A(ll)” option allows you to add a monitoring request for all monitors in one
operation.
NOTE
Using the “All monitors” option when creating a request has the benefit of applying the request
to a new class of supported hardware resource that you may add to your system. This ensures
that the new hardware is automatically included in your monitoring strategy.
To add a monitoring request:
1. Run the Hardware Monitoring Request Manager by typing:
/etc/opt/resmon/lbin/monconfig
2. From the main menu selection prompt, enter A.
3. At the Monitors selection prompt, enter the number assigned to the monitor for which you are creating a
request. The numbers for the monitors are listed on the screen. You can enter multiple numbers
separated by commas, or you can enter “a” to create a request for all monitors.
4. At the Criteria Threshold prompt, enter the number for the desired severity level. See Table 2-15 on
page 48.
5. At the Criteria Operator prompt, enter the number for the desired operator. See Table 2-14 on page 47.
6. At the Notification Method prompt, enter the number for the desired method. See Table 2-14 on page 47.
If the notification method you selected requires you to input additional information, do so when promoted.
7. At the User Comment prompt, enter any comments about this monitoring request that you desire. This
text will be sent with events which match this monitoring request. This feature is NEW, as of the June
2000 release.
8. At the Client Configuration File prompt, enter (C)lear to use the default client configuration file, or enter
A(dd) to specify the name of a specific client configuration file for this request. This file allows you to
enable/disable events, set thresholding criteria and severity levels for events on a per-client basis (for
example, for HP Support Applications). Adding a client configuration file at this prompt does not create or
edit the file; it merely sets up the monitoring request to use the file. Unless you have a specific client that
requires a client configuration file, choose (C)lear (the default). This feature is NEW, as of the June 2000
release. It is only valid for monitors that are Multiple-View (Predictive-Enabled).
9. Save the request when prompted.
Repeat the above steps for each new monitoring request.
NOTE
Are monitoring requests automatically applied to new hardware resources?
Because monitoring requests are created at the monitor level and not at the hardware instance
level, a new hardware resource added to the system inherits the same monitoring requests
assigned to other hardware of the same type. This ensures that new hardware is automatically
46
Chapter 2
Installing and Using Monitors
Adding a Monitoring Request
added to the monitoring configuration. When you restart the system or execute the IOSCAN
utility (thus performing a real/hard IOSCAN), the new hardware will be included in event
monitoring.
If you add a new class of supported hardware resource to your system, any monitoring requests
that apply to All monitors are used for the new hardware, ensuring that your hardware is
protected immediately from undetected failure.
For hardware monitoring to recognize new devices, the new devices must be properly added
and configured, so that they are recognized by the kernel (ioscan -k must see them).

Criteria
Thresholds
This value identifies the severity level used in conjunction with the
criteria operator to generate an event message. See Table 2-15 on
page 48, for an explanation of severity levels.
Criteria
Operators
This value identifies the arithmetic operator used with the criteria
threshold to control what events are reported. Valid operators are:
< (less than)
<= (less than or equal to)
> (greater than)
>= (greater than or equal than)
! (not equal to)
Operators treat each severity level as a numeric value assigned as
follows:
Critical = 5
Serious = 4
Major warning = 3
Minor warning = 2
Informational = 1
The criteria operators allow you to direct events of several severity
levels using the same notification method. For example, to direct both
Serious and Critical events using the same method, you would use a
condition of >= Serious.

Verifying Hardware Event Monitoring
Verifying Hardware Event Monitoring
Once you have created the monitoring requests you need for your system, you may want to verify that they
are working as you expect. The most effective way of verifying hardware event monitoring is to simulate a
hardware failure or event. Depending on the hardware, you can do this by removing a disk from an array,
unplugging a cable, turning off the hardware resource, using known defective media, etc.
The simulated fault should generate event messages using all the notification methods you have specified. If
it does not, check the monitoring requests and make sure they are configured properly.

Checking Detailed Monitoring Status
Checking Detailed Monitoring Status
This option lets you view the detailed information for all active monitoring requests. This information is
organized by resource instance, and lists all the monitoring requests currently applied to each instance.
Unlike the option to Show Monitoring Requests which displays all the monitoring requests that have been
created using the Hardware Monitoring Request Manager, the detailed status displays only the requests that
are currently active. For example, you can create a monitoring request for a monitor that is inactive, but it
will not be displayed in the detailed list.
A monitor that is not active will be identified with a status of NOT MONITORING. Any monitor that does not
have any resources to monitor will be inactive.
NOTE
Where Did the TCP Requests Come From?
You may notice that most resources have a TCP monitoring request that you did not create.
This request is created automatically by the Peripheral Status Monitor (PSM) to allow it to
gather event information from each monitor.
The following sample is representative of the types of entries displayed for detailed monitoring status.
For /storage/events/disks/default/10_12_5.2.0:
Events >= 1 (INFORMATION) Goto TEXTLOG; file=/var/opt/resmon/log/event.log
Events >= 4 (MAJOR WARNING) Goto SYSLOG
Events >= 4 (MAJOR WARNING) Goto EMAIL; addr=root

Retrieving and Interpreting Event Messages
Retrieving and Interpreting Event Messages
Event messages generated by hardware monitoring can be delivered using a variety of notification methods.
To simplify receiving event messages you may want to use the email and/or textfile notification methods. Both
of these methods, which are included in the default monitoring, receive the entire content of the message so
you can read it immediately.
Methods such as console, syslog, and SNMP alert you to the occurrence of an event but do not deliver the
entire message. You are required to retrieve it using the resdatautility. For these methods, the event
notification will include a message similar to the following:
Execute the following command to obtain event details: /opt/resmon/bin/resdata
-R 392036357 -r /storage/events/tapes/SCSI_tape/10_12_5.0.0 -n 392036353 -a
It is important that you execute the command exactly as indicated, including the two critical number fields
that are indexes for the resdataentries.

The Detailed Picture of Hardware Monitoring
Components from Three Different Applications
Hardware event monitoring involves components from three different applications:
•
Event Monitoring System (EMS) provides the framework for event notification. EMS was originally
developed to support system monitoring, but the existing framework is used to manage hardware event
monitoring as well.
•
•
Hardware event monitoring components include the event monitor, associated configuration files, and the
hardware monitoring request manager.
Support Tools Manager provides the low-level error handling components that are also used for recording
and viewing system errors.
Hardware Monitoring Request Manager
Hardware event monitoring requests are created and managed using the Hardware Monitoring Request
Manager program. This tool allows you to easily create monitoring requests for all the hardware event
monitors running on your system. The Hardware Monitoring Request Manager uses all the notification
methods supported by Event Monitoring Service (EMS), giving you the ability to create a consistent
notification strategy for both system resources and hardware resources. The Hardware Monitoring Request
Manager is also used to enable or disable hardware monitoring.
Once created, all hardware event monitoring requests are handled by EMS, which uses the request settings to
determine how an event should be reported.

Chapter 3
Detailed Description
The Detailed Picture of Hardware Monitoring
EMS Hardware Event Monitor
The EMS hardware event monitor is the key component in the event monitoring architecture. An event
monitor is a daemon process, running in the background continuously. The event monitor watches all
instances of the hardware resources it supports, waiting for the occurrence of any failures or other unusual
events. The monitor may use polling, asynchronous event detection, or both.
When an event occurs, the monitor alerts EMS and passes it the appropriate event message. The event
monitor also tells the PSM about the event. If the event is serious enough the PSM will change the status of
the hardware to DOWN.
Two configuration files control the operation of each hardware event monitor:
•
Global monitor configuration file. The settings defined in this file are used for all hardware event
monitors, unless overridden by a monitor-specific file.
•
Monitor-specific configuration file. Each monitor includes its own configuration file with optimized
settings. The settings defined in the monitor-specific file override corresponding settings defined in the
global configuration file.
NOTE
The settings defined by the monitor-specific configuration file have been carefully selected to
meet the needs of most users. It is possible to alter these settings, but it is not recommended
unless you fully understand the implications of doing so. For information on modifying the
monitor-specific configuration files, see Chapter 5, “Hardware Monitor Configuration Files.”
NOTE
As of the June 2000 release, several of the hardware monitors have been converted to be
“multiple-view” (Predictive-enabled). These monitors use a different file for configuration, the
Client Configuration File.
Polling or Asynchronous?
Hardware event monitors employ two methods of tracking events: polling and asynchronous event detection.
A monitor may use one or both of the methods to detect events.
Using polling, a monitor checks the status of its hardware resources at regular intervals, typically 60
minutes. Any unusual condition reported by the hardware will trigger an event by the monitor. The polling
interval is selected to provide reasonable detection without impacting system performance. The main
disadvantage of polling is that an event will not be detected until the next time the resource is polled, which
makes the system vulnerable to another hardware failure.
Asynchronous detection allows a monitor to detect an event when it occurs, usually during an I/O to the
device. An event typically results in a log entry made by the hardware device driver. The monitor detects the
log entry and initiates the event notification. Asynchronous event monitoring allows immediate notification
and response to a critical situation.
Startup Client
The startup client launches and configures the hardware event monitors each time the system is started, or
following the execution of the IOSCAN utility (thus performing a real/hard ioscan). The startup client starts
each monitor and configures its hardware resources using a set of default monitoring requests.
62
Chapter 3
Detailed Description
The Detailed Picture of Hardware Monitoring
Each monitor has its own startup configuration file, which contains the default monitoring requests and
any customized requests created using the Hardware Monitoring Request Manager. During system startup,
following the execution of the IOSCAN utility (thus performing a real/hard ioscan), or when managing
requests using the Hardware Monitoring Request Manager, the startup client reads each configuration file
and creates the monitoring requests defined by the entries in the file. The Hardware Monitoring Request
Manager updates the contents of the startup configuration file when you add or modify monitoring requests.
Peripheral Status Monitor (PSM)
The sole purpose of the peripheral status monitor (PSM) is to convert events detected by a hardware event
monitor to changes in hardware resource status. This conversion is required for use with MC/ServiceGuard in
controlling package failover. When an event occurs, the PSM determines if it is serious enough to warrant a
change in hardware resource status to DOWN. If it is, the PSM alerts EMS, which then informs
MC/ServiceGuard.
Event Monitoring Service (EMS)
The event monitoring service (EMS) provides the framework within which hardware monitoring takes
place. EMS manages the monitoring requests created for each monitor. When an event occurs, the associated
monitor alerts EMS and passes it an event message. EMS then uses the monitoring request to determine how
(or if) the event message should be delivered. EMS manages all hardware event notification.
EMS also provides the graphical interface for creating and managing PSM monitoring requests. Like event
monitoring requests, all PSM monitoring requests are managed by EMS.
Other system monitors are available for EMS at additional cost. For more information on EMS and available
monitors, see Using EMS HA Monitors (B5735-90001).

Startup Process (in Detail)
The following steps describe the process used to start the hardware monitoring. The startup process is
illustrated in Figure 3-2 on page 65.
The startup process is managed by the startup client (startcfg_client). The startup client is run when the
system is restarted, following the execution of the IOSCAN utility (performing a real/hard ioscan), when the
enable monitoring command is executed from the Hardware Monitoring Request Manager, or when
monconfig changes the monitor requests.
1. When the system is restarted, following the execution of the IOSCAN utility (performing a real/hard
ioscan), or when the enable monitoring command is executed, the Hardware Monitoring Request
Manager (monconfig) calls the start up client (startcfg_client).
2. The startup client reads the contents of a monitor startup configuration file and registers the monitoring
requests contained in the file with the EMS registrar. This causes the associated monitor to start running.
If monitoring is already enabled, the startup client unregisters all current monitoring requests, then
reads the content of the startup configuration files and registers the requests again.
3. The monitor examines the IOSCAN (ioscan -k) results table to determine if there are any hardware
resources on the system that it is responsible for monitoring. If it finds such resources, the monitor
continues to run. If it does not find any resources, the monitor stops.
4. If the monitor supports asynchronous event detection, it registers with diaglogd, indicating what types
of errors the monitor wants to receive. The monitor may specify a product description, product number, or
driver name.
5. The startup client then repeats the process for all monitor startup configuration files.

Asynchronous Event Detection (in Detail)
The following steps describe the process involved in asynchronous event detection. The asynchronous
detection is illustrated in Figure 3-3 on page 68.
1. A device driver detects an error during an I/O with the device.
2. The device driver passes the error information, including SCSI sense data, to the diag2pseudo driver,
which adds information indicating the instance of the driver logging the error to the message header. The
error message is then passed to the diaglogddaemon used by STM to monitor recoverable errors.
3. Diaglogduses the instance information to retrieve hardware path, product type, product name, and
driver name information from the message header. This information is used to determine which monitor,
if any, the information should be passed to. The error message is also written to the raw error log
(/var/stm/logs/os/log#.raw.cur).
During startup, each asynchronous monitor registered with diaglogd, indicating what types of errors the
monitor wants to receive. The monitor may specify a product description, product number, or driver name.
If a monitor is registered to receive the error, the message is passed to it.
4. The monitor decodes the error to determine if an event should be reported. If an event should be reported,
the monitor passes the event message to Event Monitoring Service (EMS).
5. EMS uses the current monitoring requests for the monitor to determine what action to take. Based on the
requests, the event is reported using the specified notification method(s).
Event Decoding
In addition to monitoring hardware, many of the EMS hardware monitors also act as message decoders for
logtool, which is used to read the contents of the raw error log. If the error uses an EMS hardware monitor
as the decoder, logtoollaunches a new instance of the monitor to perform the decoding. In this way all
events that have occurred on the device, including those IGNORED by the monitor, can be viewed.
67
Chapter 3
Detailed Description
The Detailed Picture of Hardware Monitoring
Event Polling (in Detail)
The following is the process used for gathering event information using polling. The polling process is
illustrated in Figure 3-4 on page 70.
1. At the interval defined by the polling value in the monitor configuration file, the monitor communicates
with all the devices it is currently monitoring. The monitor sends pass-thru commands to all SCSI
devices, and uses the appropriate protocol for other types of devices. The exact type and sequence of
communication used during a polling operation is monitor-specific.
2. Each device responds to the message from the monitor by returning data indicating its status. The
information returned in response to polling is not entered in the raw error log.
3. The monitor interprets the information from the device to determine if an event should be reported. If an
event should be reported, the monitor passes the event message to EMS.
4. EMS uses the current monitoring requests for the monitor to determine what action to take. Based on the
requests, the event is reported using the specified notification method(s).
FC-AL Hub and FC Switch Polling Processes
Unlike the other EMS hardware monitors, the FC-AL hub monitor and FC switch monitor use SNMP to
gather information from the hubs or switches they are monitoring. Using the hub or switch IP addresses
defined in the hub or switch configuration files, the monitor polls the devices at the defined polling interval
(60 minutes by default) using SNMP.
The reporting of events is handled in the same way as all other monitors. Event information gathered by the
hub and switch monitors does not get written to the raw error log, and the hub and switch monitors do not act
as a decoder for logtool.
PA Memory Monitor Polling
The memory monitor polling process uses different components to retrieve event information. The memory
monitor polling process is illustrated in Figure 3-5 on page 71.
1. At regular intervals (default 60 minutes) the memlogddaemon polls the memory hardware.
2. If a single-bit error is detected, memlogduses the values from the memory configuration file to determine
the severity of the error, and then passes the appropriate event message to the memory monitor.
The error is also logged in memlog, which can read using logtool. All decoding of memory error messages
is performed by memlogd.
3. The memory monitor determines if the event should be reported. If the event should be reported, the
monitor passes the event message to Event Monitoring Service (EMS).
4. EMS uses the current monitoring requests for the memory monitor to determine what action to take.
Based on the requests, the event is reported using the specified notification method(s).

Peripheral Status Monitor Overview
Peripheral Status Monitor Overview
The primary function of the Peripheral Status Monitor, or PSM, is to convert hardware events into changes in
device status. These changes in status can then be used by MC/ServiceGuard to control package failover.
The information in Chapter 2, “Installing and Using Monitors,” described how to configure your system to
detect hardware events using the Monitoring Request Manager. In this chapter you will learn how to use the
PSM to convert these events into changes in device status using the EMS GUI, which is accessed through
SAM.
NOTE
Can I Use the PSM Without MC/ServiceGuard?
Even if you are not using MC/ServiceGuard, you can still use the PSM to create hardware
status monitoring requests using EMS. This allows you to get notification for changes in
hardware resource status, much as you can for other EMS monitors. If you create a PSM
monitoring request, when a hardware event occurs you may be alerted twice—once for the
event itself and again if the event caused the status of the resource to change to DOWN.
74
Chapter 4
Using the Peripheral Status Monitor
How Does the PSM Work?
How Does the PSM Work?
The PSM converts hardware events detected by the EMS Hardware Monitors to “UP” or “DOWN” status,
which is used by MC/ServiceGuard in controlling package failover. Figure 4-1 on page 76 illustrates how the
PSM works with the other components of hardware monitoring.
Because hardware event monitors detect and report the occurrence of events rather that resource status, a
method is required to alert MC/ServiceGuard when a hardware resource has a status that may impact data
availability. The PSM provides this functionality, serving as the interface between the hardware event
monitors and MC/ServiceGuard.
Some monitors can determine when a problem has been corrected and the hardware is functioning properly.
These monitors automatically alert the PSM when the hardware is fixed, and the PSM will return the state of
the hardware to UP. Other monitors do not have the capability of determining when the hardware problem is
corrected. With these monitors it will be necessary for the user to use the set_fixedutility to manually
return the operational state to UP.
75
Chapter 4
Using the Peripheral Status Monitor
How Does the PSM Work?
PSM Components
The PSM comprises the following components, which are installed along with the hardware event monitors.
Each component has its own man page containing detailed information about its operation.
• psmctd- the Peripheral Status Client/Target daemon used to monitor the state of hardware resources.
• psmmon- the utility used to monitor the state of resources recognized by the psmctd daemon.
• set_fixed- the utility used to manually change the status of a hardware resource from DOWN to UP.
Used only for monitors that do not the have capability to perform this operation automatically.
PSM States
The PSM can assume the three status conditions shown in the following table. These are the values you can
use to define a monitoring request.
Table 4-1
PSM Status
Condition
Interpretation
Up
The hardware is operating normally.
Down
An event has occurred that indicates a
failure with the hardware.
Unknown
Cannot determine the state of the
hardware. This state is treated as DOWN by
the PSM.
PSM Resource Paths
Selecting a hardware resource for PSM monitoring requires the selection of the correct resource path. The
resource class path is the means by which EMS identifies system resources. Resources are divided into
classes and subclasses based on their type or function. For example, the resource classes for PSM monitoring
include adapters, connectivity, and storage.
The resource path ends with the resource instance, which uniquely identifies a hardware resource. There is
an instance for each individual hardware resource supported by the monitor. The resource instance is
typically the hardware path to the device (e.g., 10_12_5.0.0), but it may also be a device name as in the case of
AutoRAID disk arrays.
EMS monitoring requests are applied at the resource instance level. This is unlike event monitoring requests
created using the Hardware Monitoring Request Manager, which are applied at the monitor level. Thus when
creating an EMS monitoring request you must select the specific resource you want to monitor. An all (*)
option allows you to apply a PSM monitoring request to all current instances of the hardware. A monitoring
request will not be applied to new hardware added to the system after the request is created.
PSM resource class path names are structured as follows:
/top_level_resource_class/status/subclass/subclass/instance
For example, the PSM resource class path for a SCSI tape device at hardware path 10_12_5.0.0 would be:
/storage/status/tapes/SCSI_tape/10_12_5.0.0
The PSM resource class path for an AutoRAID disk array with an ID of 000000105781 would be:
/storage/status/disk_arrays/AutoRAID/000000105781

Chapter 4
Using the Peripheral Status Monitor
Configuring MC/ServiceGuard Package Dependencies with the PSM
Configuring MC/ServiceGuard Package Dependencies with the PSM
The PSM allows you to create MC/ServiceGuard package dependencies for resources monitored by EMS
Hardware Monitors.
To use the PSM with MC/ServiceGuard, you configure one or more of the resource instances available in the
PSM as MC/ServiceGuard package dependencies. This creates an EMS monitoring request that monitors the
status of the resource and alerts MC/ServiceGuard if the status of the resource changes.
Here are some examples of how PSM monitoring requests might be used:
•
In a cluster where one copy of data is shared between all nodes in a cluster, you may want to failover a
package if the host adapter has failed on the node running the package. Because buses, controllers, and
disks are shared, package failover to another node because of bus, controller, or disk failure would not
successfully run the package. To make sure you have proper failover in a shared data environment, you
must create identical package dependencies on all nodes in the cluster. MC/ServiceGuard can then
compare the resource “UP” values on all nodes and failover to the node that has the correct resources
available.
•
In a cluster where each node has its own copy of data, you may want to failover a package to another node
for a host adapter, bus, controller, or disk failure. In this sort of cluster of web servers, where each node
has a copy of the data and users are distributed for load balancing, you can failover a package to another
node with the correct resources available. Again, the package resource dependencies should be configured
the same on all nodes.
NOTE
You should create the same requests on all nodes in an MC/ServiceGuard cluster.
There are two methods for configuring PSM package dependencies; using SAM, or by editing the package
configuration file.
79
Chapter 4
Using the Peripheral Status Monitor
Configuring MC/ServiceGuard Package Dependencies with the PSM
Configuring Package Dependencies using SAM
The procedure assumes you have taken the necessary steps to create the package to which you will be adding
resource dependencies. Complete instructions for configuring MC/ServiceGuard clusters and packages are
provided in Managing MC/ServiceGuard.
To create a package resource dependency:
1. From the command line, start the graphical version of SAM by typing: sam
2. Double-click the Clusters icon.
3. Double-click the High Availability Clusters icon.
4. Double-click on the Package Configuration icon.
The High Availability Clusters screen is displayed showing all requests configured on that system.
5. From the Actions menu, select either Create/Add a Package or Modify Package Configuration.
Depending on which option you selected, the Create/Add Package screen is displayed or the Modify
Package screen is displayed.
6. If you have not yet done so, specify a Package Name and Node and Specify a Package SUBNET Address.
Then click on “Specify Package Resource Dependencies…” to add PSM resources as package
dependencies. The Package Resource Dependencies screen is displayed.
7. To make a package dependent on an EMS HA Monitors resource, click Add Resource. The Add Resources
screen is displayed listing all the installed resources discovered by MC/ServiceGuard. The resource
classes used for PSM monitoring are adapters, connectivity, storage, and system.
8. Double-click on the appropriate PSM resource class, then on the status class, then on the remaining
resource subclasses until the PSM monitor instances are displayed in the Resource Names list. Select
the desired PSM resource and click OK. A Resource Parameters screen is displayed
9. Enter an appropriate Resource Polling Interval value. This value determines how often EMS checks
the PSM for changes in status. The value you select for polling should be related to how critical the
resource is to system operation. You may want to use a short polling interval for critical resources, and a
longer interval for non-critical resources. Be aware that polling can impact system performance, so avoid
using a short polling interval for all resources.
10. Select UP from the list of Available Resource Values, then click < — Add — .
11. Click OK to add the package dependency.
Package failover will now occur if the status of the resource changes from UP.

Using the Peripheral Status Monitor
Configuring MC/ServiceGuard Package Dependencies with the PSM
Configuring Package Dependencies by Editing the Configuration File
You can also add PSM package dependencies by editing the package configuration file in
/etc/cmcluster/pkg.ascii. See the Managing MC/ServiceGuard for details on modifying this file.
When using the MC/ServiceGuard commands (e.g., cmapplyconf) to specify the use of the PSM Resource
Monitor, the section of the package configuration file that has the keyword “RESOURCE_NAME” must be
uncommented and set to the value of the resource name of interest. The PSM has a different resource path
name for hardware resource being monitored.
For example, assume you want to create a dependency on a SCSI disk that has a resource path of
/storage/status/disks/default/10_0_5.0.0. You want to use a polling interval of 10 seconds and identify
UP as the only state that will not cause failover. The following entry would be added to the configuration file
to add a package dependency for this disk:
RESOURCE_NAME /storage/status/disks/default/10_0_5.0.0

monitoring requests. Because it is a state monitor rather than an event monitor, the process and options
available for creating PSM requests with EMS are identical to those for the other system monitors available
for EMS.
To create a PSM monitoring request:
1. From the command line, start the graphical version of SAM by typing: sam
2. Double-click the Resource Management icon.
3. Double-click on the Event Monitoring Service icon.
The Event Monitoring Service main screen is displayed showing all monitoring requests configured on the
system. Included are any PSM monitoring requests you may have created, and any requests created for
other EMS monitors that may be running on your system. If you have not created any requests, the field
area of the screen will be empty.
4. From the Actions menu select Add Monitoring Request.
The top level resource classes are displayed. The resource classes used for PSM monitoring are adapters,
connectivity, storage, and system.
5. Double-click on the appropriate resource class, then on the status class, then on the remaining resource
subclasses until the PSM monitor instances are displayed in the Resource Instance list.
6. Select the desired PSM resource instance and click OK. If there are multiple instances, you can select the
* (All Instances) option to apply the monitoring request to all instances of the selected resource. All
Instances is a convenient way to create many requests at one time.
The Monitoring Request Parameters screen is displayed for the selected PSM resource.
7. Using the various parameter fields available, define the monitoring request. A description of the various
parameters and how they are used is included in the following section.
Although there are many possible ways to define the monitoring request, the following settings are
recommended for PSM requests:
•
•
•
•
Notify conditions set to “Notify When value is…Not Equal Up (0)”
Options set to Initial and Return
Polling Interval set to an appropriate value
Notify via set to the desired notification method
8. Click OK to save the monitoring request. The request will be added to those in the Current Monitoring
Requests screen.
Repeat the above steps for each new PSM monitoring request. It will be necessary to create a new monitoring
request for each notification method.

Using the Peripheral Status Monitor
Monitoring Request Parameters
Monitoring Request Parameters
The following information describes in detail the monitoring request parameters and offers tips on how to use
them.
Specifying When to Send Event - <Notify>
One of the first steps in creating a monitoring request involves specifying the conditions under which you
want to be alerted. The following options are available for selecting when to send an alert.
Table 4-2
PSM Status
When value
is…
You define the conditions under which you wish to be notified for a
particular resource using an operator (=, not equal, >, >=, <, <=)
and a value returned by the monitor (UP, DOWN, UNKNOWN).
Text values are mapped to numerical values.
When value
changes
This notification might be used for a resource that does not change
frequently, but you need to know each time it does.
At each
interval
This sends notification at each polling interval. It would most
commonly be used for reminders or gathering data for system
analysis. Use this for only a small number of resources at a time,
and with long polling intervals of several minutes or hours; there is
a risk of affecting system performance.
Determining the Frequency of Events - <Options>
If you select the When value is… from the <Notify> options, the Options box is displayed. Select one or more
of these options:
Table 4-3
Initial
PSM Status
Use this option for testing a new request to ensure it is sending alerts
to the desired destinations.
Repeat
Use this option for urgent alerts. The Repeat option sends an alert at
each polling interval as long as the notify condition is met. Use this
option with caution; there is a risk of high CPU use or filling log files
and alert windows.
Return
Use this option to track when a condition returns to its previous
value.
These Options are not available if you have selected When value changes or At each interval from the
<Notify> list. In these cases the options default to:
•
•
Repeat and Return - Not selected
Initial - Selected
83
Chapter 4
Using the Peripheral Status Monitor
Monitoring Request Parameters
Setting the Polling Interval - <Polling Interval>
The polling interval specifies how often EMS will check the PSM for changes in hardware status. The polling
interval is the maximum amount of elapsed time before EMS will be aware of a change in status for the
hardware resource being monitored. A short polling interval will ensure that you have recent data. However,
a short polling interval may use more CPU and system resources. You must weigh the importance of being
able to respond quickly against the importance of maintaining good system performance.
Some considerations include:
•
MC/ServiceGuard monitors resources every few seconds. You may want to use a short polling interval (30
seconds or less) when it is critical that you make a quick failover decision.
•
•
You may want a polling interval of 5 minutes or so for monitoring less critical resources.
You may want to set a very long polling interval (4 hours) to monitor failed disks that are not essential to
the system, but which should be replaced in the next few days.
Selecting Protocols for Sending Events - <Notify Via>
Using the <Notify via> option, you can specify the method EMS uses to send events. The options are:
opcmsg ITO
This option sends messages to ITO applications via the opcmsg daemon. IT Operation 4.0 or above must be
installed on the resource server for this option to display.
The ITO message severity options are:
•
•
•
•
•
Critical
Major
Minor
Warning
Normal
A specified severity other than Normal is returned under the following conditions:
•
•
The When value is . . . condition evaluates to TRUE
The When value changes condition evaluates to TRUE
See the HP OpenView IT/Operations Administrators Task Guide (Part Number B4249-90003) for more
information on configuring notification severity.
Templates for configuring IT/Operations and Network Node events can be found on the Hewlett-Packard
High Availability public web page at http://www.hp.com/go/ha.
To set the opcmsg ITO:
1. Specify the notification type from the <Notify> list.
2. Select the opcmsg ITO option from the <Notify via> list.
3. Select the severity from the <Severity> list, (Critical, Major, Minor, Warning, Normal).

"1.3.6.1.4.1.11.2.3.1.7.0.9" - Problem Event w/Critical Severity notification
Specify the ITO message severity for both normal and abnormal events:
•
•
•
•
•
Critical
Major
Minor
Warning
Normal
A specified severity other than Normal is returned under the following conditions:
Certain SNMP trap monitoring requests can map directly to severity levels. For these requests, a toggle
button <Map severity from value> is displayed. If this is selected, options selected from <Severity> are
ignored.
•
•
The When value is… condition evaluates to TRUE
The When value changes condition evaluates to TRUE
To set the SNMP trap:
1. Specify the notification type from the <Notify> list.
2. Select the opcmsg ITO option from the <Notify via> list.
3. Select the severity from the <Severity> list, (Critical, Major, Minor, Warning, Normal).
TCP and UDP
This option sends TCP or UDP encoded events to the target host name and port indicated for that request.
Thus the message can be directed to a user-written socket program.
To set the TCP or UDP conditions:
1. Select the TCP or UDP option, as appropriate, from the <Notify via> list.
2. Specify the target host name and the port.
email
This option sends event notification to the specified email address

An abnormal event message (error) is returned under the following conditions:
•
•
The When value is . . . condition evaluates to TRUE
The When value changes condition evaluates to TRUE
To set for a system log notification:
1. Select the Syslog option from the <Notify via> list.
Console
This option sends event notification to the system console.
To set for a console notification:
1. Select the Console option from the <Notify via> list.
Textlog
This option sends event notification to the specified file.
To set for an text log notification:
1. Select the Textlog option from the <Notify via> list.
2. Specify the filename and path in the File Path field.
A default path, /var/opt/resmon/log/event.log, is displayed when the Textlog option is selected.
Note that EMS HA Monitors will not create the file, it will add notifications to an existing file.
Adding a Notification Comment - <Comment>
The notification comment is useful for sending task reminders to the recipients of an event. For example, you
may want to add the name of the person to contact if an event occurs. If you have configured
MC/ServiceGuard package dependencies, you may want to enter the package name as a comment in the
corresponding request.

Using the set_fixed Utility to Restore Hardware UP State
Using the set_fixed Utility to Restore Hardware UP State
Most hardware event monitors cannot detect when a hardware failure has been repaired and the resource has
been returned to normal operation. Consequently, these monitors cannot alert the PSM to change the status
of its hardware resources from DOWN to UP. It is necessary for you to manually change the status of the
hardware resources using the set_fixedutility included with the PSM. To determine if a monitor requires
use of the set_fixedutility, refer to the monitor descriptions in Chapter 6, “Monitor Data Sheets.”
The set_fixedutility includes its own man page describing how to change the state of the resource.
NOTE
Make sure you have repaired the problem before you use the set_fixedutility to return the
hardware resource status to UP. If the hardware is not repaired, the change in status to UP
may cause MC/ServiceGuard to erroneously assume the hardware is working properly.
To restore the operating state of a resource to UP:
1. If necessary, list the hardware resources that currently have a status of DOWN by typing:
/etc/opt/resmon/lbin/set_fixed -L
2. Set the status of the DOWN hardware resource to UP by typing:
set_fixed -n resource_name
The resource_name is the status resource path name to the hardware resource that has been repaired. When
specifying the resource_name you can use wildcards such as “*” to indicate all instances.
Example 4-1
Example of Using set_fixed
The following example sets to UP the status of the SCSI tape device at hardware path 10_12_5.0.0
set_fixed -n /storage/status/tapes/SCSI_tape/10_12_5.0.0
The following example sets to UP the status of all AutoRAID disk arrays.
set_fixed -n /storage/status/disk_arrays/AutoRAID/*

Hardware Monitor Configuration Files
5 Hardware Monitor Configuration Files
Several configuration files are used to control the operation of each hardware event monitor. The operation of
the monitor can be altered by editing the contents of the various configuration files. Before altering the
contents of a configuration file, you should have a thorough understanding of what effects the changes will
have on monitor operation. The following paragraphs should provide the understanding you need for using
configuration files properly.
CAUTION
Before editing any configuration file, create a backup copy of it. This will allow you to recreate
the original environment if the changes you make do not produce the desired results.

Chapter 5
Hardware Monitor Configuration Files
Overview
Overview
Understanding Multiple-View and Non-Multiple-View Monitor Classes
EMS Hardware Monitors are divided into two classes: Multiple-View and Non-Multiple-View. Multiple-View
monitors allow you to specify different event messages (for the same monitor) to one or more targets
(“clients”). Targets may have different requirements for events, so event messages can be configured to be
unique for each target. Non-Multiple-View monitor event messages are generated in the same way for all
targets.
Within these two monitor classes, there are configuration files that control the operation of each hardware
event monitor. Both classes of monitors use the Global and Monitor-specific configuration files (.cfg) to
configure required monitor settings such as POLL_INTERVAL. In addition, Multiple-View monitors also use
the Client Configuration file (.clcfg). The client configuration file allows you to configure different event
messages for multiple targets.
Monitor Configuration File Types
The following configuration files control the operation of each hardware event monitor:
•
Global monitor configuration file. The settings defined in this file are used for all monitors, unless
overridden by a monitor-specific or client configuration file.
•
Monitor-specific configuration file. Each monitor includes its own configuration file with optimized
settings. Settings defined in the monitor-specific file override comparable settings defined in the global
configuration file.
•
Client configuration file. With Multiple-View hardware monitors, you can create a different Client
Configuration File (*.clcfg) for each target. Settings defined in the client configuration file override
comparable settings defined in either the global or monitor-specific configuration files.
NOTE
For Multiple-View monitors, settings not defined in the Client Configuration File (*.clcfg) such
as the POLL_INTERVAL, must be defined in either the Global or Monitor-specific
configuration file (*.cfg).
94
Chapter 5
Hardware Monitor Configuration Files
Client Configuration File
Client Configuration File
As of the June 2000 release, several of the hardware monitors have been converted to be multiple-view. These
monitors use an additional file for configuration, the Client Configuration File (for example,
default_disk_em.clcfg.)
The immediate purpose of this change is to enable HP Support Applications to work with hardware monitors.
There will also be long-term benefits, as well.
Clients: Targets for Events
When a hardware monitor detects an event, it can send an event message to one or more targets (“clients”).
Previously, EMS hardware monitors generated events in the same way for all targets. The problem is that
different targets, such as HP Support, may have different requirements for events.
The June 2000 release introduced the Multiple-View feature to several monitors; this feature will be added to
most hardware monitors in future releases.
Creating a Client Configuration File (*.clcfg)
With Multiple-View hardware monitors, you can create a different Client Configuration File (*.clcfg) for each
target. In this file, you can specify:
•
•
The text to be included in event messages.
“Qualification requirements”: the time or value thresholds a problem must meet in order to generate an
event. For example, the default time threshold might be to send an event if the problem is seen six times
in 24 hours; however, HP Support may want to see the event three times in 24 hours. Another example:
the default value threshold might be to send the event when the value associated with the problem is
greater than or equal to 80, but HP Support may want to see the event when the value is greater than or
equal to 70.
•
•
Events to be enabled/disabled for a given target. For example, event 1 may be enabled for target #1, but
disabled for target #2.
Severity level for an event sent to a given target. For example, event 3 may have a severity level of
CRITICAL for target #1, but a severity level of MAJOR_WARNING for target #2.
The default Client Configuration File (*.clcfg) is:
/var/stm/config/tools/monitor/default_MONITOR_NAME.clcfg
For example:
/var/stm/config/tools/monitor/default_disk_em.clcfg
The Client Configuration File for the HP Support Applications client would be:
/var/stm/config/tools/monitor/xxx_disk_em.clcfg
Verifying Monitors with a Test Event
As of the June 2000 release of the diagnostics, a standalone program is available to cause multiple-view EMS
hardware monitors to generate a test event:
/opt/resmon/bin/send_test_event
95
Chapter 5
Hardware Monitor Configuration Files
Client Configuration File
OR
/etc/opt/resmon/lbin/send_test_event
The program was created for HP Support Applications to ensure that the communication mechanism from the
monitor to HP Support is working. However, it can be used by customers to ensure the same thing: that the
communication mechanisms from the monitor to their notification method (email, event log, SNMP trap, etc.)
are working.
The program will not work with monitors that have not been updated to be multiple-view. In the long-term,
all monitors are planned to be updated to be multiple-view.
Before the send_test_event program can be run, the monitors must be enabled and configured. (That is, when
you run monconfig, it should say that monitoring is enabled and when you do a “Check”, the requests show
up.)
The test event is #103 with a default severity of "INFORMATION". To test delivery to notification targets
that by default only receive higher severity events (e.g. syslog or email to root, which receive
"MAJOR_WARNING" or higher events only), you must edit the .clcfg file for the monitor to change the
severity of event #103.
For more information on the command, see the manpage for send_test_event.
Sample Client Configuration File
The following is a sample of a client configuration (.clcfg) file.
# There are 4 types of entries in this file.
HOST_ID, DEV_ID, EQ,
# CLCFG_VERSION. Each entry starts with the appropriate tag,
# followed by one or more colon separated fields. The number of fields and
# valid values for each field depends
# on the tag.
#
# Each entry in this file must be one line. Meaning, no returns can be
# put in the middle of a line. This may mean that the EQ entries will wrap.
# Text fields in the entries are case sensitive.
#
# Host ids that should be added to the event. This information will
# be added in the order the tags are listed
# Possible host ids are:
# host_model_num
# host_os_version
# host_fw_version
# host_serial_num
# host_sw_id
# host_ems_version
# host_stm_version
# Example:
# HOST_ID: host_ems_version : host_stm_version
HOST_ID:host_model_num:host_ems_version:host_stm_version
# Device ids that should be added to the event. This information will be
# added in the order the tags are listed
# NOTE: these are specific to this monitor
# Example:
# DEV_ID: dev_product : dev_qualifier
DEV_ID:dev_pdev:dev_inq_vendor:dev_inq_prod:dev_fw_version:dev_serial_num
#DEV_ID:dev_pdev:dev_comp_tag2
# Event qualification entries for events generated by this monitor.
# NOTE: the event numbers are specific to this monitor.
# Example:

# event number
#
# severity : the severity of the event. Valid values are:
#CRITICAL
#SERIOUS
#MAJOR_WARNING
#MINOR_WARNING
#INFORMATION
#
# enable flag : whether the event is enabled. Valid values are:
#TRUE - event is enabled
#FALSE - event is not enabled
#
# suppression time : time, in seconds, to suppress generation and trending
# for this event after generating the event.
# Valid values are:
#NOT_USED - Never suppress the event
#1 - maxint - number of seconds to suppress
#
# time window: amount of time, in seconds, event must be seen to
# qualify event. Valid values are:
#NOT_USED - time window thresholding not used
#ANY - time window thresholding used but no time window specified
#1-maxint - time need to see threshold events to qualify
#
# threshold : number of times in time window event must be seen to qualify
# event. Valid values are:
#1-maxint
# NOTE: to configure event to always be generated every time it is seen,
# threshold should be set to 1 and time window should be set to "ANY"
# value threshold X, operator X : value thresholds to qualify event.
# Valid values for value threshold depend on the type of value associated
# with the event. However, predefined value of "NONE" means this value
# threshold is not used. Valid values for operator X are:
#NO_OP - this operator not used
# >, < , >=, <=,==, !=.
# These values are used to qualify the event using the following logic:
# value threshold 1 operator 1 value operator 2 value threshold 2
# For example, if the value is an integer and want to qualify event if
# value is between 60 and 70, inclusive, the entry would be:
# 60 : <= : <= 70. If the value is an integer and want to qualify event
# if value is > 70, the entry would be : NONE : NO_OP : > : 70.

Hardware Monitor Configuration Files
Monitor-Specific and Global Configuration Files
Monitor-Specific and Global Configuration Files
The common operating parameters defined by the monitor-specific and global configuration files for all
non-multiple-view monitors include:
•
Polling Interval - identifies the frequency at which the monitor polls the hardware for status. This value
is selected to provide current device status without seriously impacting system performance.
•
Repeat Frequency - indicates how often the same event should be reported. Events that continue to exist
should not overburden the system with a continuous stream of messages. A value of once a day is used as
the default repeat frequency.
•
•
Severity Action - determines whether the severity level will be passed to EMS for reporting or ignored.
Event Definition - identifies each event handled by the monitor, defines its severity level, and determines
what action the monitor will take when the event occurs. Actions include ignoring the event, passing it on
to EMS, or using the default action defined by the Severity Action setting.
NOTE
When Do Changes Made to a Configuration File Take Effect?
Changes made to a monitor-specific configuration file are invoked at the next polling interval or
when an event occurs, which ever comes first. In either of these situations, the monitor reads
its configuration file for any changes and implements any new settings.
File Names
Global configuration file: /var/stm/config/tools/monitor/Global.cfg
The file naming convention for the monitor-specific configuration files is:
/var/stm/config/tools/monitor/monitor_name.cfg
monitornameis the name of the monitor executable
File Format
Settings in the device configuration file use the following conventions:
•
Configuration settings consist of a term defining the characteristic to be configured, followed by a value
assigned to the term.
For example, POLL_INTERVAL 60
•
•
There must be at least one space between the term and each value.
Comments begin with the pound character (#) and continue until the end of the line. A comment may
occur on a line by itself, or after a blank space following the value in a configuration entry.
For example, either of the following are valid comments:
# Valid values for severity_name are:
SEVERITY_ACTION CRITICAL NOTIFY # notify on critical events
100

Hardware Monitor Configuration Files
Monitor-Specific and Global Configuration Files
Table 5-1 lists the common fields used to define monitor configuration settings. In addition to the common
parameters, some monitors include other parameters in their configuration file. Any additional configuration
parameters used by each monitor are listed in the monitor descriptions in the data sheets for the hardware
event monitors available on the Web at http://docs.hp.com/hpux/onlinedocs/diag/ems/emd_summ.htm.
NOTE
An HP-UX man page is available for each monitor. To access the man page, type (where
monitornameis the executable file listed in the data sheet): man monitorname

Considerations for Modifying the Monitor Configuration File Settings
The default configuration settings for each monitor have been carefully selected to provide efficient
monitoring for most systems. However, it may be necessary to modify these settings in specific situations.
Here are some considerations for altering the configuration settings.
NOTE
Settings in the Global.cfgconfiguration file apply to all monitors, so you should avoid
changing these settings. If you need to change the parameters for a monitor, do so using the
monitor-specific configuration file.
Monitor Configuration File Settings
Event Definition
You may want to alter the event definition in a monitor-specific configuration file to change the severity level
assigned to an event, or to suppress reporting of an event.
NOTE
Be aware that any changes you make to the event definition will impact all instances of the
monitor's hardware resources. You cannot modify the behavior of a specific hardware resource.
For example, if a disk array is repeatedly reporting the same event and you would like to
suppress it, you can do so by changing the event definition. But the change will suppress that
event even if it occurs on a different disk array. This may not be the result you want.
•
•
Changing the severity level assigned to an event. If you feel that the severity level assigned to an
event does not reflect its importance in your environment, you can make the event more or less
important. For example, if an event is currently assigned a severity level of MAJOR WARNING but from
experience you feel it represents a CRITICAL condition, you can change the DEFINE_EVENT setting for
the event.
Ignoring an event. By default, all events are reported. If you are getting repeated notification for an
event, you can ignore the event. When the condition that caused the event is corrected, you can once again
set the event for notification.
Severity Action
By default, all severity levels are reported to EMS. This default was selected because even lower level events
such as INFORMATION may provide valuable data for identifying trends that could lead to more serious
conditions. Consequently, it is recommended that you do not suppress the reporting of any events.
102
Chapter 5
Hardware Monitor Configuration Files
Monitor-Specific and Global Configuration Files
However, if you do want to suppress the reporting of less important events, you can change the severity action
to IGNORE. This will affect all events in that category, and all instances of the monitor's hardware resources.
Polling Interval
If you need more frequent polling to isolate a potential problem with the hardware, the polling interval can be
reduced. Be aware that more frequent polling may impact system performance, so you may want to shorten
the polling period only temporarily until the problem is solved. Avoid using a low polling interval for all
monitors or system performance may suffer.
Repeat Frequency
If you need to be alerted to an event frequently, the repeat frequency can be reduced. The default repeat
frequency is once a day.

Hardware Monitor Configuration Files
Startup Configuration File
Startup Configuration File
Each hardware event monitor has its own startup configuration file which contains the monitoring requests
currently defined for the monitor. At startup, following the execution of the IOSCAN utility (performing a
real/hard ioscan), or when using the Hardware Monitoring Request Manager (monconfig) to manage
monitoring requests, the entries in the startup configuration file are used to create monitoring requests for
the monitor.
Each monitoring request in the startup configuration file is applied to all instances of the monitor's hardware
resources. An identical set of default requests are included in the startup configuration file for each monitor.
You modify the contents of the startup configuration file using the Hardware Monitoring Request Manager.
When you use the Hardware Monitoring Request Manager to create or manage monitoring requests, the
results are stored as an entry in the monitor's startup configuration file. If you have selected the All Monitors
option for the request, an entry will be made in the startup configuration file for all the monitors.
NOTE
When Do Changes Made to a Startup Configuration File Take Effect?
Changes made to a startup configuration file are invoked when the system is restarted,
following the execution of the IOSCAN utility (performing a real/hard ioscan), or when the
Hardware Monitoring Request Manager is used to manage monitoring requests. For example,
when you add, delete, or modify a monitoring request using the Hardware Monitoring Request
Manager, the changes to the startup configuration file will take effect immediately.
File Names
The file naming convention for the startup configuration files is:
/var/stm/config/tools/monitor/monitorname.sapcfg
monitornameis the name of the monitor executable.
File Format
Entries in the startup configuration file use the following conventions:
•
•
•
The startup configuration file contains monitoring request entries identifying the notification method and
reporting criteria for the monitor. Each entry contains records consisting of a keyword, followed by a colon
(:), followed by the value assigned to the keyword. For example, Criteria Threshold: INFORMATION
'MONITOR' must be the first keyword found in each entry, but the remaining records in the entry are not
order-dependent. For example:
MONITOR: /storage/events/disk_arrays/FW_SCSI
Comments begin with the pound character (#) and continue until the end of the line. A comment may
occur on a line by itself or after a blank space following the value for a keyword.
For example, either of the following are valid comments:
# Default monitoring entries
Target Type: SYSLOG
# Send events to syslog
Table 5-2 identifies the keywords that make up each entry in the startup configuration file. Each entry must
contain the keywords identified as required.

Chapter 5
Hardware Monitor Configuration Files
Startup Configuration File
Considerations for Modifying the Startup Configuration File Settings
While you can edit the contents of the startup configuration file directly, the better approach is to use the
Hardware Monitoring Request Manager (monconfig) to create and manage your monitoring requests. Using
the monitoring request manager you can create requests for multiple monitors simultaneously. And the
Hardware Monitoring Request Manager ensures that all request entries are formatted correctly.
The only benefit that editing the configuration file offers is that you can use the COMMENTsetting to add
information that will be included with the event.
Table 5-2
Startup Configuration File Entries
Keyword
MONITOR (required)
Values
Description
A valid event monitor
resource path
Identifies the hardware
event monitor to which
the entry applies. All
entries must use the
resource path for the
monitor being
configured.
Note: This must the first
keyword in each entry
Criteria Threshold (required) Valid values include:
Defines the severity
level used as the
notification criteria
threshold.
CRITICAL
SERIOUS
MAJOR_WARNING
MINOR_WARNING
INFORMATIONAL
Criteria Operator (required)
Valid operators are:
This value identifies the
arithmetic operator
used with the criteria
threshold to control
what events are
reported. The operator
treats each severity
level as a numeric value
assigned as follows:
%< (less than)
%<= (less than or equal to
)
> (greater than)
>= (greater than or equal
to)
! (not equal to)
Critical = 5
Serious = 4
Major warning = 3
Minor warning = 2
Informational = 1
The event severity
received is the left
operand and the
Criteria Threshold value
is the right operand.

Chapter 5
Hardware Monitor Configuration Files
Peripheral Status Monitor (PSM) Configuration File
Peripheral Status Monitor (PSM) Configuration File
Interaction between the PSM and a hardware event monitor is controlled by a PSM configuration file. This
file defines what severity levels will result in DOWN status being reported, and what action, if any, is
required to return the hardware to UP status. Any hardware event monitor that does not include a PSM
configuration file will not be monitored by the PSM.
NOTE
When Do Changes Made to a PSM Configuration File Take Effect?
The PSM checks its configuration files every 10 seconds, so any changes will be invoked when
the file is checked. If the hardware configuration has changed and the PSM is communicating
with all the monitors to determine what their resources are, it may take a few minutes for any
changes to a configuration file to take effect.
File Names
The file naming convention for the PSM configuration files is:
/var/stm/config/tools/monitor/monitorname.psmcfg
monitornameis the name of the monitor executable.
File Format
The PSM configuration file contains a single entry using the following conventions:
•
The entry consists of keywords defining the characteristic to be configured, followed by a value assigned
to the keyword.
•
•
There must be at least one space between the keyword and each value.
Comments begin with the pound character (#) and continue until the end of the line. A comment may
occur on a line by itself or after a blank space following the value for a keyword.
Table 5-5 identifies the keywords that make up the entry in the PSM configuration file. The entry must
contain the keywords identified as required.
121
Chapter 5
Hardware Monitor Configuration Files
Peripheral Status Monitor (PSM) Configuration File
Considerations for Modifying the PSM Configuration File
•
The only change you should consider making to the PSM configuration file is redefining the severity
levels which cause a change to DOWN status. By default, SERIOUS and CRITICAL events will result in
a DOWN status. If you want to include lower level events, or restrict the status change to just CRITICAL
events, you can do so using the DOWN_SEVERITY_THRESHOLDand DOWN_SEVERITY_OPERATORsettings.
NOTE
Do not attempt to change the value of MONITOR_STATE_HANDLING. Changing this value may
result in unpredictable results when attempting to reset the hardware status of the resource to
UP.
It is recommended that you not lower the severity levels that can cause a DOWNstatus. If you do,
events that do not warrant a status of DOWNmay cause it to occur.

Pushing EMS Hardware Monitors configuration to multiple systems
Pushing EMS Hardware Monitors configuration to multiple systems
To push EMS Hardware Monitors configuration to multiple systems, do the following:
•
Do the configuration on one system via monconfig (creates appropriate
/var/stm/config/tools/monitor/*.sapcfg)
•
Do additional manual edits, if any, in the other configuration files:
/var/stm/config/tools/monitor/*.cfg, default_*.clcfg
/var/stm/config/tools/monitor/Global.cfg
/var/stm/data/tools/monitor/
NOTE
The default values in these files work; it would only be if you had specific configurations
you wanted to change and push out that you would need this step.
•
For each system where the new configuration is desired, copy all /var/stm/config/tools/monitor/*.cfg,
default_*.clcfg, *.sapcfg to new system except any file with the name “predictive” or “rst” (ISEE) or “ovfn”
(HPEN) in it. Execute /etc/opt/resmon/lbin/startcfg_client to enable the new configuration.
NOTE
If OPC (OpenView) configuration is desired, the initial configuration must be done on a
system where OPC is installed. Otherwise, it will not be available for use in monconfig.

Chapter 6
Special Procedures
Fibre Channel Arbitrated Loop Hub Monitor
Initial Monitor Configuration
Unlike the other EMS Hardware Monitors, the FC-AL hub monitor requires some initial configuration before
it will function. Because a FC-AL hub is not part of the host's configuration, the host cannot detect any hubs
during startup. You must tell the hub monitor what hubs you want it to monitor. This is done by defining two
settings in the hub monitor configuration file, HUB_COUNTand HUB_X_IP_ADDRESS.
Configuring the FC-AL Monitor Configuration File
To configure the FC-AL monitor configuration file complete the following steps:
Step 1. Determine which hubs you want the monitor to be responsible for. Record the IP address for each of
these hubs.
Step 2. Open file /var/stm/config/tools/monitor/dm_fc_hub.cfgin an ASCII text editor.
Step 3. Add the following line to the file:
HUB_COUNT n
Replace “n” with the value that reflects the number of hubs for which the monitor will be
responsible. For example, the following line would monitor 5 hubs:
HUB_COUNT 5
Step 4. Add the following line to file:
HUB_X_IP_ADDRESS nn.nn.nnn.nnn
Change the placeholder “X” to the number 1, and replace the “nn” fields with the IP address of the
hub that will be designated as hub 1.
The completed line will look similar to the following:
HUB_1_IP_ADDRESS 15.43.214.101
Step 5. If multiple hubs will be monitored, replicate the line from step 4 for each hub, changing the hub
number and IP Address for each. When you are done, the number of lines should equal the number
defined in the HUB_COUNTsetting. For example, the following lines would configure the monitor for
three hubs:
HUB_COUNT 3
HUB_1_IP_ADDRESS 15.43.214.101
HUB_2_IP_ADDRESS 15.43.214.171
HUB_3_IP_ADDRESS 15.43.214.184
Step 6. Save the file.
Step 7. To invoke the changes made to the hub configuration file, you must use the Enable Monitoring
option of the Hardware Monitoring Request Manager, even if monitoring is already enabled. The
Enable Monitoring option runs the startup client, which reads the contents of the configuration file
and starts the hub monitor to begin monitoring of the FC-AL hubs. See “Enabling Hardware Event
There are other settings in the configuration file that can be changed to customize the operation of the FC-AL

Adding or Removing an FC-AL Hub
Adding or removing a hub from the monitor configuration involves changing the same configuration file
settings described in the preceding procedure, HUB_COUNTand HUB_X_IP_ADDRESS.
Changing the FC-AL Hub Monitoring Configuration
To change the FC
Step 1. Determine the IP address for each hub your are adding or deleting.
Step 2. Open file /var/stm/config/tools/monitor/dm_fc_hub.cfgin an ASCII text editor.
Step 3. Locate the following line in the file and change value “n” to reflect the new number of hubs to be
monitored:
HUB_COUNT n
Step 4. If you are adding a hub, add the following line to file:
HUB_X_IP_ADDRESS nn.nn.nnn.nnn
Change the placeholder “X” to the number you want assigned to the hub (typically the next
sequential number available), and replace the “nn” fields with the IP address of the hub.
The completed line will look similar to the following:
HUB_5_IP_ADDRESS 15.43.214.101
Repeat this step for each hub you are adding.
Step 5. If you are removing a hub, locate the HUB_X_IP_ADDRESSline for the hub to be removed and delete
it from the file. If you deleting multiple hubs, delete the line for each one.
Step 6. Save the file.
Step 7. To invoke the changes immediately, run the Hardware Monitoring Request Manager and select the
(E)nable Monitoring option. This option runs the startup client, which will cause the changes to the
