This release notes describes the changes made to the EMS Hardware Monitors for the HP-UX 11i v3 (11.31), September 2007 release.

Overview

Hardware event monitoring enables you to eliminate undetected hardware failures that can interrupt system operation or cause data loss. The EMS Hardware Monitors are an important set of tools for maintaining system availability. The EMS Hardware Monitors enable you to monitor operations of a wide variety of hardware resources, and alert you immediately in the event of a failure or if an unusual event occurs. These monitors are included in the OnlineDiag bundle.

Hardware event monitoring provides a high level of protection against system hardware failure.

Note: On the HP-UX 11i v3 operating system, Online Diagnostics does not support tape drives. Although some of the Support Tools Manager (STM) tools may work 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

What Is New in This Version

The DS2500 Enclosure Monitor (gazemon) is introduced on HP 9000 and Itanium-based systems running HP-UX 11i v3. The gazemon monitor supports the DS2500 enclosure services.

Configuring Hardware Monitoring

The EMS Hardware Monitors are installed along with the Support Tools Manager (STM). Once the monitoring software is installed, monitoring is enabled automatically.

By default, monitors report events with severity levels, MAJOR_WARNING, MINOR_WARNING, SERIOUS, CRITICAL, or INFORMATION in the following ways:

• Written to /var/adm/syslog/syslog.log file
• Sent to the root E-mail address

Events are stored in the /var/opt/resmon/log/event.log file.

To configure, enable, or disable hardware event monitoring, run the monitoring request manager.

The Peripheral Status Monitor (PSM) is configured using the Event Monitoring Service (EMS). For more information on how to configure PSM, see Configuring Monitors with the EMS GUI at:
http://docs.hp.com/en/diag/ems/ems_gui.htm

Changes

Following are the changes made to the EMS Hardware Monitors for the current release:

• Changes to all Monitors
• Changes to Individual Monitors
• Changes to Configuration Files
• Changes to Monitoring Request Manager

• Changes to all Monitors
  
  • Not applicable
• Changes to Individual 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 to HP 9000 systems only:
    • JAGag26932
      The dm_chassis monitor reports old events when the process table is full. This problem is fixed.
  • CMC Monitor (cmc_em)
    • QXCR1000582558
      The cmc_em monitor is enhanced to support the Automatic Process Recovery (APR) functionality. The cmc_em monitor generates Event 100661 when a recoverable Machine Check Abort (MCA) occurs, and the processor qualifies for a Dynamic Processor Resilience (DPR) action. Subsequently, the DPR action is initiated on the faulty processor.
  • Core Hardware (dm_core_hw)
    The following change applies to HP 9000 and Itanium-based systems:
    • JAGag33013
      Events generated by the dm_core_hw monitor are not notified because there are two error thresholds. This problem is fixed.
    The following change applies to HP 9000 systems only:
    • JAGag37222
      The dm_core_hw monitor supports the following systems:
      • rp7440
      • rp8440
      • 9000/800/SD16
      • 9000/800/SD32
      • 9000/800/SD64
  • Core Hardware for HP 9000 and Itanium-based Intelligent Platform Managment Interface (IPMI) systems (ia64_corehw)
    • JAGag09544
      The ia64_corehw monitor does not generate events when the SENSOR_RESCAN_INTERVAL condition is met. This problem is fixed. The monitor now generates reminder events.
  • Core Hardware Monitor - Asama (ipfcorehw_asama)
    • Not applicable
  • Core Hardware Monitor - Hitachi (ipfcorehw_hitachi)
    • Not applicable
  • CPE Monitor (cpe_em)
    The following change applies to Itanium-based systems only:
    • JAGag28122
      The event details of Event 100220 and Event 100221 incorrectly indicate that the cell is faulty. The event details are modified to fix this problem.
  • CPU Monitor (lpmc_em)
    The following change applies to HP 9000 systems only:
    • JAGag33954
      On vPar systems that are managed by the Global Workload Manager (gWLM), the lpmc_em monitor generates Event 100 and Event 101 if gWLM adds or deletes processors. The monitor is modified to prevent it from generating these events.
  • CPU Monitor - Hitachi (cmc_em_hitachi)
    • Not applicable
  • Disk Array FC60 Monitor (fc60mon)
    • Not applicable
  • Disk Monitor (disk_em)
    • Not applicable
  • DS2500 Enclosure Monitor (gazemon)
    
    • The gazemon monitor is introduced in the HP-UX 11i v3 September 2007 release.
  • Fibre Channel Adapter Monitor for FCD Driver-based Adapters (dm_ql_adapter)
    • Not applicable
  • Fibre Channel Adapter Monitor for A6795A/A5158A Adapters (dm_TL_adapter)
    • Not applicable
  • Fibre Channel Switch (dm_fc_sw)
    • Not applicable
  • Forward Progress Log (FPL) Monitor (fpl_em)
    The following changes apply to HP 9000 and Itanium-based systems:
    • JAGag16195
      The Time Stamp of Event 676 is incorrect. This problem is fixed.
    • JAGag37586
      The fpl_em monitor does not generate pre-boot events. A new value, PRE_BOOT_FLAG, is added in the global config file (fpl_em.cfg) to fix this problem.
  • High Availability Disk Array Monitor (ha_disk_array)
    • Not applicable
  • High Availability Storage System (dm_ses_enclosure)
    The following change applies to HP 9000 and Itanium-based systems:
    • JAGag35642
      Event 601 and Event 603 are reported incorrectly. This problem is fixed.
  • Memory (dm_memory)
    • Not applicable
  • Memory IA64 (memory_ia64)
    The following changes apply to Itanium-based systems only:
    • JAGag39454
      The memory_ia64 monitor is modified to generate Event 1400 when the Page Deallocation Table (PDT) is 100% full.

    • Not applicable
  • UPS Monitor (dm_ups)
    
    • Not applicable
• Changes to Configuration Files
  
  • Not applicable
• Changes to Monitoring Request Manager
  The following change applies to HP 9000 and Itanium-based systems:
  • JAGag26113
    The monconfig daemon is modified to not depend on the swlist command to obtain the EMS version.

Known Problems

---

• 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.
