These release notes cover the March 2002 release of Support Plus for HP-UX 11i/11.00/10.20 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 (HP-UX 11i, 110.00 and 10.20).

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, 11.00, or 10.20 (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/monconfig .

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 2002 release include:

• Changes to Multiple Monitors
• Changes to Individual Monitors
• Changes to Platform and Interface
• Customer-Vi sible 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).
  
  • The catalog file for armmon referred to "SCSI_TEMPLATE". It has been modified to replace that character string with "armmon".
• Chassis Code Monitor (dm_chassis).
  
  • There is a new dm_chassis clcfg file, which redefines a chassis code event severity.
  • JAGae00453
    Fixed syntax error in default_dm_chassis.clcfg file, which changed the severity field label for serious events from "Serious" to "SERIOUS".
  • There is a new configuration file for the chassis code monitor.
• CMC Monitor (cmc_em).
  
  • N/A
• Core Hardware Monitor (dm_core_hw)
  
  • A fix was made which allows us to ignore intermittent GSP communications failures, as generating events on these has become an irritant in the field.
• Core Hardware for Itanium (ia64_corehw).
  
  • N/A
• Disk Array FC60 Monitor (fc60mon).
  
  • N/A
• Disk Monitor (disk_em).
  
  • N/A
• Fibre Channel Adapters (dm_FCMS_adapter).
  
  • N/A
• Fibre Channel Adapter Model A5158 Monitor (dm_TL_adapter).
  
  • N/A
• Fibre Channel SCSI Multiplexer (dm_fc_scsi_mux).
  
  • N/A
• Fibre Channel Switch (dm_fc_sw).
  
  • N/A
• High Availability Disk Array Monitor (ha_disk_array) .
  
  • N/A
• High Availability Storage System (dm_ses_enclosure)
  
  • JAGae11212
    Changes were made to support DS2300 and DS2405 devices.
• Kernel Resource Monitor (krmond)
  
  • N/A
• LPMC Monitor (lpmc_em).
  
  • JAGae02927
    Because of changes in the firmware, the newer PIM data can't be decoded by the existing LPMC monitor. The code thinks that the data it received is incorrect because the lengths don't agree.
  • JAGad99544
    1. On SuperDome systems, the number of iCOD CPUs is not stored in the same location in the NV ram. For this reason, the CPU library routine to access the # of iCOD CPU fails, and monitor is led to think that there are no iCOD CPUs. Therefore, during DPR action, no spare processor is activated. The new design now does not depend on # of iCOD CPUs. Any CPU that is Inactive, but not deactivated by the LPMC monitor, will be activated during DPR action.
  • Changed code to support SPU_DEALLOCA_HW_FAILURE when processor is deallocated by LPMC monitor. Needs the O/S patch.
• Memory Monitor (dm_memory).
  
  • N/A
• Peripheral Status Monitor (PSM).
  
  • Fixed psmmon to recover from a failure to determine if psmctd is running. Prior to fix, if psmmon couldn't determine if psmctd was running, it would return RM_ERROR_TYPE on all requests for device state. It would continue to report this error, even when it later was able to determine psmctd was running.
• Remote Monitor (RemoteMonitor).
  
  • N/A
• SCSI Card Monitor (scsi123_em).
  
  • N/A
• SCSI Disk (scsi_disk).
  
  • JAGad91761, JAGad95500, JAGad94330, JAGad94427 JAGad85036
    A fix was made to stop polling devices such as Magneto-Optical disks, Mitsumi CD-ROMs, and HP DVD ROMs -305.
• SCSI Tape Monitor (dm_stape).
  
  • N/A
• System Status Monitor (sysstat_em)
  
  • N/A
• UPS Monitor (dm_ups).
  
  • N/A

Changes to Platform and Interface

• N/A

Customer-Visible Interface Changes

• JAGad94752
  Added a description of what a monitoring request is to the text displayed by monconfig.

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 one of the
following patches:
HPUX 10.20/s800 : PHCO_24153 (supersedes PHCO_23830)
HPUX 11.00      : PHCO_24172 (supersedes PHCO_23831)
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_19031 (HP-UX 10.20) or 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, pharaymon_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, sdisk_exec.cfg, and haraymon_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".
