These release notes cover the March 2004 release of Support Plus for HP-UX 11.0 running on S800/S700 systems.

NOTE: As of the September 1999 release, the name of the Diagnostic/IPR Media has been changed to Support Plus. In addition, the format has changed so that there is a separate CD-ROM for each version of the operating system (e.g., HP-UX 11.0).

NOTE: The HP Storageworks SDLT 160/320 GB Tape Drive and HP Ultrium 460 External Tape Drive are NOT SUPPORTED by the OnlineDiag product. Even though some STM tools may function with these devices, they are still NOT SUPPORTED. The diagnostic tools and utilities that DO SUPPORT these devices are the HP StorageWorks Library and Tape Tools (L&TT). These tools can be downloaded, free of charge, at:

Overview

Included on the Support Plus CD-ROM 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 products and be alerted immediately if any failure or other unusual event occurs. Hardware event monitoring is available to users running HP-UX 11i and 11.00 (IPR 9902 and later).

Hardware event monitoring provides a high level of protection against system hardware failure. By using hardware event monitoring, you can virtually eliminate 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. Once the monitoring software is installed, monitoring is automatically enabled.

By default, messages regarding major warning, serious and critical events that occur on hardware being monitored will be:

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

All events will be stored in /var/opt/resmon/log/event.log.

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

The Peripheral Status Monitor (PSM) and the The Kernel Resource Monitor (krmond) are configured differently. They use the EMS GUI. See: http://docs.hp.com/hpux/onlinedocs/diag/ems/ems_gui.htm

Changes

Changes in the EMS Hardware Monitors for the the March 2004 release include:

• Changes to Multiple Monitors
• Changes to Individual Monitors
• Changes to Platform and Interface
• Customer-Visible Interface Changes

Changes to Multiple Monitors

• N/A

Changes to Individual Monitors

Changes to each monitor are described below. (Monitors are listed in alphabetical order.)

• AutoRAID Disk Array (armmon).
  
  • JAGae82991
    Whenever a new 12H device is connected to the server, the customer needs to check to see if ARMServer is running. Once this check is done, the customer then needs to issue the arraydsp -R command, so that the server will identify the device. This needs to be done before the monitor starts monitoring the device.
• Chassis Code Monitor (dm_chassis).
  
  • N/A
• Core Hardware Monitor (dm_core_hw)
  
  • N/A
• Core Hardware Monitor for Itanium (ia64_corehw).
  
  • JAGae95681
    When the OnlineDiag bundle is removed and re-installed, the monitor starts to write to the log file with '00' extension. This has been fixed.
• CPU Monitor (lpmc_em).
  

  Note: As of the June 2002 release, the LPMC Monitor (lpmc_em) was renamed to "CPU Monitor". The binary name is still lpmc_em. The name was changed to reflect the monitor's enhancement to check floating-point functionality in the CPU.

  • JAGaf02580
    The location of the CPU Datafile, that is created and used by the lpmc_em event monitor, has been changed from "/var/stm/data/tools/monitor/lpmc_em.dat" to "/var/stm/logs/monitor/lpmc_em.dat".
• Disk Array FC60 Monitor (fc60mon).
  
  • JAGae90990
    Previously, only one event was being generated for any number of GHS enabled/disabled disks. The change made in the configuration file enables reporting of all the GHS events, either enabling or disabling GHS disks, in FC60 storage devices.
  • JAGae97568
    The modified catalog file lists the steps to kill and restart the AM60Srvr.
  • JAGae82991
    Whenever a new fc60 device is connected to the server, the customer needs to check to see if AM60Srvr is running. Once this check is done, the customer then needs to issue the amdsp -R command, so that the server will identify the device. This needs to be done before the monitor starts monitoring the device.
  • JAGae97568
    The catalog file has been modified to list the steps necessary to kill and restart the AM60Srvr.
  • JAGaf01421
    The /etc/opt/resmon/log directory is deleted 24 hours after the fc60mon monitor starts. This problem is fixed.
• Fast Wide SCSI Disk Array (fw_disk_array)
  • N/A
• Disk Monitor (disk_em).
  
  • disk_em reported a very large number of errors, corrected with delay. This has been fixed in this release.
• Fibre Channel Adapters (dm_FCMS_adapter).
  
  • N/A
• Fibre Channel Adapter Model A5158 Monitor (dm_TL_adapter).
  
  • N/A
• Fibre Channel Adapter Model A6826A Monitor (dm_QL_adapter)
  • N/A
• Fibre Channel SCSI Multiplexer (dm_fc_scsi_mux).
  
  • N/A
• Fibre Channel Switch (dm_fc_sw).
  
  • N/A
• Forward Progress Log Monitor (fpl_em)
  
  • N/A
• High Availability Disk Array Monitor (ha_disk_array).
  
  • N/A
• High Availability Storage System (dm_ses_enclosure)
  
  • N/A
• iSCSI Device Adapter (dm_iscsi_adapter)
  • N/A
• Kernel Resource Monitor (krmond)
  
  • N/A
• LPMC Monitor (lpmc_em).
  As of the June 2002 release, the LPMC Monitor (lpmc_em) was renamed to "CPU Monitor". The binary name is still lpmc_em. The name was changed to reflect the monitor's enhancement to check floating-point functionality in the CPU. For more information, see CPU Monitor (lpmc_em).
• Memory Monitor (dm_memory).
  
  • JAGae57879
    When the /etc/protocols file was missing, the dm_memory monitor looped around with high CPU usage. This has been fixed. It will now use the default protocol number for the protocol.
• Peripheral Status Monitor (PSM/psmmon).
  
  • N/A
• Remote Monitor (RemoteMonitor).
  
  • N/A
• SCSI Card Monitor (scsi123_em).
  
  • N/A
• SCSI Cascade Monitor (scsi_cascade).
  
  • N/A
• SCSI Disk (scsi_disk).
  
  • N/A
• SCSI Tape Monitor (dm_stape).
  
  • JAGae96244
    Code has been modified to fix the SIGSEGV error for dm_stape.
• System Status Monitor (sysstat_em).
  
  • N/A
• UPS Monitor (dm_ups).
  
  • N/A

Changes to Platform and Interface

• JAGae46500
  When monconfig utility is used to add a monitoring request, the monoconfig utility prints an irrelevant error, after the help output. Now the code is modified to correct this problem.

Customer-Visible Interface Changes

• N/A

Known Problems

---

CAUTION: UPS Monitor May Need a Patch

In some cases, the UPS monitor (dm_ups) will not function and will instead generate event 45 (formerly event 42) with the text:

Probable Cause / Recommended Action:

The monitor was unable to locate the fifo pipe that should have been
created by ups_mond.  Therefore, information about the ups cannot be sent
to the monitor.

You need version (80.1.2.3) of ups_mond or greater.  To update your
system with the correct version of ups_mond, install the
following patch:

HPUX 11.11      : PHCO_23832

To fix the problem, load the indicated patch or load the HWE patch bundle which contains this patch. For HP-UX 11i, the ups_mond patch PHCO_23832 is also distributed on the Sept 01 OE.

This problem will affect most systems with a UPS when the September 2001 diagnostics are installed. The only systems not affected will be those which are being updating from certain versions of the diagnostics (September 2000 through March 2001) and which do not have patch PHCO_19040 (HP-UX 11.00) installed.

CAUTION: Monitoring Changes for disc30, sdisk and disk array devices

As of IPR 9902 (Feb 99 release), there has been a change to the way that monitoring is done for disc30, sdisk and the HA Disk Array Models 10, 20, and 30FC.

Formerly, the "diaglogd exec" programs (pdisc30_exec and psdisk_exec) handled driver error entries for these devices.

As of IPR 9902, these programs have been deleted and their functionality is now provided by the EMS Hardware Monitors.

If you had customized the configuration files for the diaglogd exec programs (disk30_exec.cfg and sdisk_exec.cfg) you may wish to re-configure the EMS Hardware Monitors to achieve the same results.

---

CAUTION: Compatibility Problem with EMS-Related Products (ServiceGuard, HA Monitors, etc.)

If you install the OnlineDiag bundle (Dec 99 or later) onto a computer running older revisions of EMS-related products, these products may experience compatibility problems. Affected products include MC/ServiceGuard, ServiceGuard OPS Edition and High Availability Monitors. The only critical problems occur with the following versions:

MC/ServiceGuard            A.10.10, A.11.01, A.11.03
ServiceGuard OPS Edition   A.11.02, A.11.03

Support Tools and the EMS hardware monitors are not affected. For complete information, see EMS Incompatibility Problem.

Monitor Dependencies

Several of the monitors have special requirements, such as patches or certain versions of firmware. In particular:

• The Fibre Channel Arbitrated Loop Hub Monitor and the Fibre Channel Switch Monitor require special configuration which is described in their data sheets in the "EMS Hardware Monitors User's Guide" (chapter 6). A patch is also required.
• A patch is required if your system includes an HP SureStore E Disk Array FC60. This patch is required to to run the EMS hardware monitor (fc60mon) or STM tools for this device.

For a list of the current required patches, see the DIAGNOSTIC.readme file for this release.

Current monitor requirements are described in the "Supported Products" page under "EMS Hardware Monitors" at http://docs.hp.com/hpux/diag . Requirements are also listed in chapter 2 of the manual "EMS Hardware Monitors User's Guide".
