This release notes reflects the changes made to the EMS Hardware Monitors for HP-UX 11.23, Dec 2005 release.

Note: No tape drives are supported by Online Diagnostics on HP-UX. 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 tool 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.

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 and critical generated by the monitors will be conveyed in the following ways:

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

All events will be 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). See: http://docs.hp.com/en/diag/ems/ems_gui.htm

Changes

The following change applies to systems based on PA-RISC platform only:

• JAGaf61014
  If there is a mistake in the suppression time of the client configuration file, events are generated every time a monitor starts, irrespective of the flag value.

The following change applies to systems based PA-RISC or Itanium platform:

• JAGaf71186
  If the system time is changed to a time that is earlier than the last boot time, all the monitors generate the following errors when the moncheck utility is executed.

  >/StorageAreaNetwork/events/SAN_Monitor ... NOT READY.
  >/system/events/cpu/cmc ... NOT READY.
  >/system/events/cpu_hitachi/cmc ... NOT READY.
  >/system/events/cpe ... NOT READY.
  >/storage/events/disks/default ... NOT READY.
  >/storage/events/disks_hitachi/default ... NOT READY.
  >/adapters/events/TL_adapter ... NOT READY.
  >/connectivity/events/hubs/FC_hub ... NOT MONITORING.
  (Possibly there is no hardware to monitor.)
  >/connectivity/events/switches/FC_switch ... NOT MONITORING.
  (Possibly there is no hardware to monitor.)
  >/adapters/events/iscsi_adapter ... NOT READY.
  >/system/events/dm_memory_asama ... NOT READY.
  

  This is to indicate that monitoring is not possible in such a scenario. The monitors are now enhanced to overcome this limitation. They continue monitoring even if the system time is changed to a time that is earlier than the last boot time.
• Memory Page Deallocation (MPD) and the memlogd daemon are not implemented on RX 4610 systems.

• Changes made to the EMS Hardware Monitors for the the Dec 2005 release include the following:
  • Changes to Monitors
  • Changes to Platform and Interface
  • Customer-viewable Interface Changes

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 changes apply only to systems running on the PA-RISC platform:

  • JAGaf69452
    The Probable Cause/Recommended Action of Event 1839 is modified.
  • JAGaf65955
    Event Summary of Event 1352 is modified.
  • JAGaf65955
    The Problem Description of Event 1352 is modified. It read "The battery on the SBCH is below the safe threshold. The battery can be replaced online." It now reads "The battery on the SBCH is below the safe threshold".

• CMC Monitor (cmc_em)

  The following change applies only to systems running on the Itanium platform:

  • The cmc_em monitor and tools now support Intel Itanium 2 processors with the Hyper-Threading feature.
• Core Hardware (dm_core_hw)
  • N/A

• Core Hardware for Itanium (ia64_corehw)

  The following changes apply to systems running on either the Itanium platform or the PA-RISC platform:

  • JAGaf46420
    The severity of Event 115002 and Event 115003 has been changed to Major Warning and Minor Warning respectively.
  • JAGaf54242
    The ia64_corehw monitor experiences a memory leak on non-cellular systems. This problem is fixed now.
  • JAGaf61202
    Event 104011 is generated when a redundant source of power supply is removed. The Generic Message of this event reads Redundancy regained. This is incorrect. The problem is fixed. The correct Generic Message now reads Redundancy lost.
  • JAGaf70658
    The ia64_corehw monitor now reports events related to temperature on rp3440 and C8000 systems.
  • JAGaf76908
    The ia64_corehw monitor configuration file is modified. It now states that the watchdog timer Power_Down and Power_Cycle settings are not applicable on cellular systems.

• Core Hardware Monitor -- Asama (ipfcorehw_asama)
  • N/A

• Core Hardware Monitor -- Hitachi (ipfcorehw_hitachi)
  • N/A

• CPE Monitor (cpe_em)

  The following change applies only to systems running on the Itanium platform:

  • The CPE Monitor now supports servers based on the HP sx2000 chipset.

• CPU Monitor (lpmc_em)

  The following change applies only to systems running on the PA-RISC platform:

  • JAGaf56907
    Event Summary of Event 100906 to Event 100910 is modified. The Dynamic Processor Resilience Action Threshold reads 32 instead of 1. This problem is fixed.

• CPU Monitor -- Hitachi (cmc_em_hitachi)
  • N/A

• Disk Array FC60 Monitor (fc60mon)

  The following changes apply only to systems running on the Itanium platform:

  • JAGaf69055
    The fc60mon monitor is modified to include the -k option during ioscan. This option reduces the time taken to scan devices in the Storage Array Network (SAN).
  • JAGaf52161
    Event 6 is generated even if fc60 is working fine. This problem is fixed. Entry for event 6 in the default_fc60mon.clcfg file is modified to report controller failure events as and when they occur.
  • JAGaf52955
    The fc60mon monitor does not generate an event when a disk fails in a Fibre Channel (FC60) array that is enabled with Global Hotspace (GHS). This problem occurs inspite of fixing the following:
    • JAGae03024
    • JAGae62769
    This problem is fixed.
  • JAGae87110
    The fc60mon monitor exits causing registrar.log messages. This problem is fixed. The monitor now logs correct signals to registrar.log avoiding the creation of spurious logs.
  • JAGaf74551
    The fcmon monitor now alerts users before resetting the controller. Also, a script is provided for resetting the controllers.

  The following change applies to systems based on PA-RISC platform only:
  
  
  • JAGaf62382 The dm_memory monitor terminates when the failure of the getsockname() call is accompanied by the errno EINTR. The monitor terminates because the dm_memory process receives a signal when it is in a blocked state. However, the system call can be reinvoked to procure a socket critical for the monitor. A maximum of 5 attempts are allowed.

• Memory IA64 (memory_ia64)

  The following changes apply only to systems running on the Itanium platform:

  • The memory_ia64 monitor does not run on the HP Virtual Machine guest operating system because the guest operating system does not interact with the physical hardware. As a result, the guest operating system does not require monitoring.

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 computer systems, does not work on RX 4610 systems. The activity log for memlogd includes a message that reads unsupported device.
  MPD cannot be implemented on the RX 4610 system because the system's design does not allow the memlogd daemon to run on it.
