DIAGNOSTIC.readme file (Jun 04)

This DIAGNOSTICS.readme file is for the June 2004 release of the Support Plus and OE Media on HP-UX 11i (11.11).

CAUTION: You must install certain patches, if applicable, before loading Online Diagnostics (Support Tools).

Overview

Support Plus and OE Media contain a complete build of the following support tools:

The support tools are all contained in a Software Depot (SD) bundle named "OnlineDiag" bundle. This bundle is distributed in the following ways:

Following is the command for listing various content levels of the depot:

swlist -l <level> -s /<mount_point>/DIAGNOSTICS/<os_release>

where <level> 
         = bundle       Bundle level listing
         = product      Product level listing
         = subproduct   Sub-product level listing
         = fileset      File set listing

      <mount_point>     Location where the CD file system
                        is mounted.

      <os_release>      The OS contents of the depot.
         = B.11.00

Support Tools Manager and ODE/LIFLOAD must be loaded after the operating system is installed. EMS Hardware Monitors are installed automatically when STM is installed.

For this release, the following apply:

Required and Recommended Patches

None

Loading Patches

You can load the patches in one of three following ways:

Known Problems

CAUTION: Info Tool causes High Priority Machine Checks (HPMCs) on K- and T-Class (HP-UX 11i only)

K-Class and T-Class computers running HP-UX 11i will experience HPMCs or Data Page Faults if you run the STM Info Tool to retrieve configuration information from HP-PB SE SCSI adapters (JAGad88317, JAGad97126).

This is due to a problem in the HP-UX 11i kernel, which is exposed when the Info Tool is run as described in the previous paragraph. To correct the problem and avoid potential HPMCs, you must load patch PHKL_25552 or its successor. This is a kernel patch and requires a system reboot.

STM exposes this problem only if the Info Tool is run on HP-PB SE SCSI adapters. STM does not expose the problem if the Info Tool is run against other I/O devices.

Problem: Clock problem causes EMS HW Monitors to go into NOT_READY state.

Symptoms:

The boot time recorded on the system is later than the current time. You can determine this by checking the system restart time in the /var/adm/syslog/syslog.log file against the time returned by the "time" command.

Cause/Action:

The most likely cause of this problem is that the EFI time was incorrectly set or modified.

If the restart time is later than the current time, the EMS HW Monitors will go into a NOT_READY state, and will not start monitoring the system until the current time on the system matches the boot time recorded. In order to determine if the monitors are in the NOT_READY state, perform the following steps:

  1. Run /etc/opt/resmon/lbin/monconfig.
  2. Choose the C)heck command.

    Each monitor will be listed, as in the example below, and the state will be NOT_READY:

            > /storage/events/disks/default ... NOT READY.
    This problem will occur on every reboot.

Workaround:

Problem: Online help may not work for xstm diagnostics.

Symptoms: In xstm (the graphical interface for online diagnostics), no online help appears when you enter a command for online help. The diagnostics themselves are still functional.

Cause/Action: Online help for xstm requires that a browser be installed on the computer. The xstm interface invokes a browser to display .htm files located in the diagnostics sub-directories on disk. (The mstm and cstm interfaces do not use a browser.)

The easiest way to install a browser is from the AR (Application Release) Media supplied with the computer.

Alternative: Using any computer, you can view online help for xstm, mstm, and cstm on the Internet at: http://docs.hp.com/hpux/onlinedocs/diag/stm/sth_summ.htm

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_27828 (supercedes PHCO_24173, 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 updated 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: 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.

Removing Diagnostics

If you wish to remove the STM online diagnostic system after it has already been installed, type:

           swremove OnlineDiag

Getting More Information

You can get more information on Diagnostics (Support Tools) in the following ways:

  1. Once you install a specific stream (e.g., HP-UX 11.11/11i), the Release Notes for that stream are available: 
       Support Tools Manager (STM): /usr/sbin/stm/Rel_NOTES.STM 
   EMS hardware monitors:  /usr/sbin/stm/Rel_NOTES.HWE
  2. For the latest information on hardware support tools, such as STM and EMS Hardware Monitors, refer to the "Diagnostics" section of Hewlett-Packard's online documentation Web site at: 
         http://docs.hp.com/hpux/diag/
    This site provides manuals, tutorials, FAQs, and other reference material. Two complete manuals ("Support Plus: Diagnostics User's Guide" and "EMS Hardware Monitors User's Guide") appear on the Web site and in the two following locations:
  3. In the DIAGNOSTICS directory under your mount point for the CD-ROM (e.g., /diagtemp/DIAGNOSTICS ). The files are named DIAG_USR.PDF and EMS_USR.PDF and can be read with the Adobe Acrobat viewer which can be downloaded from the Adobe Web site.
