These release notes cover the December 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 December 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

• JAGae23666
  The following monitors had a problem with polling time out:
  • FCMS_adapter
  • TL_adapter
  • lpmc_em
  • memory
  • scsi123
  • sysstat_em

  Now the problem is rectified to make them work properly.

Changes to Individual Monitors

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

• AutoRAID Disk Array (armmon).
  

• Chassis Code Monitor (dm_chassis).
  
• CMC Monitor (cmc_em).
  
  • N/A
• Core Hardware Monitor (dm_core_hw)
  
  • JAGae46065
    Added hversions for Pacu, Perfpak and Leone to dm_core_hw, to fix a problem that prevented the monitoring of the CPU interconnect fabric in the 875MHz cellular systems.
  • JAGae44114
    Fixed erroneous reporting of event 32 by the dm_core_hw EMS monitor in STM versions A.31.00 and A.34.00.
• Core Hardware for Itanium (ia64_corehw).
  
  • N/A

• 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.

  • JAGae46865
    There is a defect in the text of the following message passed from the lpmc monitor for events 100611 through 100614:

    Description of Error:
    
    5 Minute(s) parity errors have been detected in the Data portion of the
    Instruction Cache (I-Cache Data) in !. The operating system has recovered 
    from the errors, but this is an abnormally high failure rate. The monitor 
    will try to deactivate the processor and/or mark it for deconfiguration.  
    Another event will be generated to inform the result of the operation(s).
    

    The correct text should be as follows :

    Description of Error:
    
      2 parity errors have been detected in the Data portion of the
      Instruction Cache (I-Cache Data) in 24 hours. The operating system has recovered
      from the errors, but this is an abnormally high failure rate. The monitor
      will try to deactivate the processor and/or mark it for deconfiguration.
      Another event will be generated to inform the result of the operation(s).
    

    Even though this text is incorrect - the values for these fields in the Event Details section of the event (as shown below) are correct:

    Dynamic Processor Resilience action threshold met.
         Number of parity errors : 2
         Received in : 24 Hour(s)
    

    A fix for this problem will be released in HWE0303 release (SupportPlus March 2003 version A.36.00)

  • Added "Cache" in front of "Error(s)" for the Event Summary message.
• Disk Array FC60 Monitor (fc60mon).
  
• Fast Wide SCSI Disk Array (fw_disk_array)
• Disk Monitor (disk_em).
  
  • JAGae44953
    The new defect table is as follows:

    a) 2GB and <2GB                                         1024 (P+G) list
    b) 4GB and 9GB(Mdl # ST19171XX only)                    2048 G-list only
    
    All other 9Gb and above                                 Rely on SMART
    
    
    SMART support for New HP as well as for HP legacy HDD drives.
    

• 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) .
  
  • JAGae41541
    Fixed wrong default value in .sapcfg file, which was causing ha_disk_array not to report events.
• High Availability Storage System (dm_ses_enclosure)
  
  • JAGae32316
    There is a change made in the tlses.h file. The buffer overflow in the tlses.sl library was causing the monitor to exit with a SIGSEGV error, when DS2300 is connected with 2 controllers.

    The monitor now restarts every 2 minutes.

• 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).
  
• Peripheral Status Monitor (PSM/psmmon).
  
• Remote Monitor (RemoteMonitor).
  
• SCSI Card Monitor (scsi123_em).
  
  • N/A
• SCSI Cascade Monitor (scsi_cascade).
  
• SCSI Disk (scsi_disk).
  
• SCSI Tape Monitor (dm_stape).
  
  • JAGae40361
    A cause/action message was added to event 5000, indicating that one possible cause for this event is that the PCI card attached to the device may have been deleted using PCI OL* mechanisms or as part of a Cell OS* operation.
• System Status Monitor (sysstat_em)
  
  • JAGae33809
    This is a fix for JAGae33809, related to the sysstat_em hardware monitor. Whenever the remote system is using this monitor, it is showing the DOWN status when the remote system is down; when the remote system is up, however, it is not showing the UP status. The status can be viewed by the comand set_fixed -l. The remote machine name should be specified in the file: /var/stm/config/tools/monitor/sysstat-em.cfg
• UPS Monitor (dm_ups).
  

Changes to Platform and Interface

• Support for iSCSI decoder/monitor has been enabled.
• JAGae36855
  Fixed monconfig to remove world-write and group-write permissions on *.sapcfg files, when modifying monitoring request. Fixed monconfig, startmon_client, toggle_switch, moncheck and send_test_event to remove world-write and group-write permissions on tmp.sapcfg file.
• JAGae36855
  Fixed monconfig so that it does not add world-write permissions to *.sapcfg files when modifying monitoring requests.

Customer-Visible Interface Changes

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 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".
