This release notes reflects the changes made to the EMS Hardware Monitors for HP-UX 11.23, June 2006 release.

Note: No tape drives are supported by Online Diagnostics on the HP-UX operating system. Although some of the Support Tools Manager (STM) tools may function with tape drives, they are not supported. The diagnostic tools and utilities that support these devices are HP StorageWorks Library and Tape Tools (L and TT). These tools are available at:
http://www.hp.com/support/tapetools

Overview

Included with the OnlineDiag bundle of support tools are the EMS Hardware Monitors, an important set of tools for maintaining system availability. The EMS Hardware Monitors allow you to monitor the operation of a wide variety of hardware resources and be alerted immediately if any failure or other unusual event occurs.

Hardware event monitoring provides a high level of protection against system hardware failure. By using hardware event monitoring, you can eliminate the most undetected hardware failures that could interrupt system operation or cause data loss.

A new hardware monitor, called the Serial-Attached SCSI (SAS) Mass Storage Adapter Monitor (dm_sas_adapter), is included on Itanium-based systems. It monitors the HP SAS Mass Storage Adapter and generates events whenever an abnormal activity is detected on the device.

Configuring Hardware Monitoring

The EMS Hardware Monitors are installed at the same time as the Support Tools Manager (STM). Once the monitoring software is installed, monitoring is automatically enabled.

By default, event messages with severity levels major, warning, serious, or critical generated by the monitors are conveyed in the following ways:

• Written to /var/adm/syslog/syslog.log
• Sent to EMAIL address root

All events are stored in /var/opt/resmon/log/event.log file.

To configure, enable, or disable hardware event monitoring, run the monitoring request manager: /etc/opt/resmon/lbin/monconfig .

The Peripheral Status Monitor (PSM) and the Kernel Resource Monitor (krmond) are configured differently. They use the Event Monitoring Service (EMS) Graphical User Interface (GUI). For more information, see:
http://docs.hp.com/en/diag/ems/ems_gui.htm

Changes

Changes made to the EMS Hardware Monitors for the the June 2006 release include the following:

• Changes to the monconfig Module
• Changes to Monitors
• Changes to Platform and Interface
• Customer-Viewable Interface Changes

• Changes to the monconfig Module
  The following change applies only to PA-RISC-based systems:
  • JAGaf86545
    For security reasons, the EMS framework restricts text logging to a particular directory path on the system. The modified monconfig module verifies whether the same directory path is provided in the user input while defining the path for logging.
  The following change applies only to Itanium-based systems:
  • JAGaf83941
    The monconfig module starts and terminates individual monitors. The following options are included in the main menu:
    • Terminate selected monitor
    • Bring up terminated monitor
• Changes to Monitors
  This section describes the changes made to individual monitors. Monitors are listed in alphabetical order.
  • Chassis Code Monitor (dm_chassis)
    The following change applies only to PA-RISC-based systems:
    • JAGaf83656
      The Problem Description and the Probable Cause/Recommended Action text are modified for Event 1316.

Known Problems

---

• If the System Fault Management product is installed on your system, you must complete the following steps, before and after updating the OnlineDiag product:
  1. Type the following command to shut down the System Fault Management subsystem:

              /sbin/init.d/cimserver stop

  2. Perform the OnlineDiag update.
  3. Type the following command to restart the System Fault Management subsystem after the update is completed:

              /sbin/init.d/cimserver start

• If the maxssiz_64bit kernel parameter is set below the default value of 0x800000, it can cause the lpmc_em monitor to abort.
• The Memory Page Deallocation (MPD), which runs on most current HP-UX systems, does not work on rx4610 systems. The activity log for memlogd includes a message that reads unsupported device.
  MPD cannot be implemented on the rx4610 system because the system's design does not allow the memlogd daemon to run on it.
