Release Notes for EMS Hardware Monitors (June 1999)

These release notes cover the June 1999 (IPR 9906) release of the Diagnostic/IPR Media for HP-UX 11.00/10.20 running on S800/S700 systems.

Overview

Included on the Diagnostic/IPR Media 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 10.20 or 11.X (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:

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

Documentation

For the latest and most complete information on EMS Hardware Monitors and the Support Tools Manager (STM), see the Web page "Diagnostics":

          http://docs.hp.com/hpux/diag/
At this site, you will find Overviews, Tutorials, Quick Reference Cards, Frequently Asked Questions (FAQs), and much other material.

For complete information on installing and using EMS hardware monitors, as well as a list of supported hardware, refer to the "EMS Hardware Monitors User's Guide" available at the above site. An electronic copy of this book is also included on the Diagnostic/IPR Media CD-ROM in the /Documentation directory.

Changes

Changes in the EMS Hardware Monitors for IPR 9906 include:

Known Problems

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 dialogd 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 ServiceGuard and LockManager

From the February 1999 release (IPR 9902) onwards, the Support Tools (diagnostics) include EMS hardware monitors and EMS version A.03.00 on both HP-UX 10.20 and HP-UX 11.00.

This version of EMS is incompatible with ServiceGuard A.10.10, which includes version A.01.00 of EMS. It is also incompatible with ServiceGuard and LockManager versions A.11.01, A.11.02 and A.11.03, which include version A.02.00 of EMS.

If you run these releases of ServiceGuard or LockManager, you must upgrade them before installing the Support Tools on the February 1999 (IPR 9902) or newer releases.

On HP-UX 10.20 you should upgrade ServiceGuard to A.10.11 and on HP-UX 11.00 you should upgrade ServiceGuard or LockManager to release A.11.04 or newer.

If you do not upgrade, EMS will silently be upgraded to version A.03.00 when you install the diagnostics; ServiceGuard and LockManager will fail to work if you have any monitored resources. In this case, if you execute swverify or other SD-UX commands, you will see error messages like:

     The corequisite
     "EMS-Core.EMS-CORE,r=A.01.00,a=HP-UX_B.10.20_800,v=HP" for
     fileset "Cluster-Monitor.CM-CORE,l=/,r=A.10.10" cannot be
     successfully resolved.
If you have already loaded the diagnostics and therefore upgraded to EMS A.03.00 and are still running an incompatible release of ServiceGuard or LockManager, you should now upgrade to get your system into a supported and working state.

There is no functional difference between ServiceGuard A.10.10 and ServiceGuard A.10.11, other than support for the new version of EMS and bug fixes. Functional differences for the 11.00 releases of ServiceGuard and LockManager can be found in the release notes.

Older versions of ServiceGuard and LockManager, for example A.10.06 and A.10.07.01, do not provide any support for EMS, and so are not affected by this issue.

Monitors Provided

Monitors are provided to support the following:

In addition, a Hardware status monitor is provided to monitor the current status of the products supported by the above list.

For detailed information concerning which products are supported by which monitors and additional dependencies, check the "Diagnostics" section of Hewlett-Packard's online documentation web site: http://docs.hp.com/hpux/diag/ .

Monitor Dependencies

Several of the monitors have special requirements, such as patches or certain versions of firmware. Current 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".

Note: 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).

Defect Reporting

Use CHART to report defects in the EMS Hardware monitors. The project name is diag.hw_mon.hpux. If you don't have access to CHART, contact an HP representative to enter a defect for you.

SD Product Structure

The EMS hardware monitors are installed as part of the OnlineDiag bundle (product number B4708AA). In addition, they utilize the EMS framework, product number B7609BA.

Note: EMS Hardware Monitors are installed as part of the STM-UUT-RUN Fileset. However, the EMS Hardware Monitors are dependent on the EMS-Core and EMS-Config products and additional filesets in the Sup-Tool-Mgr Product.
