This DIAGNOSTICS.readme document covers the initial HP-UX 11i release of the hardware support tools (diagnostics) for S800/S700 systems.
The hardware support tools (diagnostics) include:
- Support Tool Manager (STM) for online diagnostics
- ODE (offline diagnostics) / LIFLOAD
- EMS hardware monitors
- EMS Kernel resource monitors
The support tools are all contained in a Software Depot (SD) bundle named "OnlineDiag". This bundle is distributed in three ways:
The hardware support tools (diagnostics) are automatically installed when the HP-UX 11i operating system is installed, via the OE CD-ROM. Later, you can install the latest versions of the support tools from Support Plus Media.
- Operating Environment (OE) CD-ROM for HP-UX 11i
- Support Plus media
- HP Software Depot website
A new version of the OE CD-ROM is released every 6 months. A new version of the Support Plus Media is released every 3 months.
Support Plus (but NOT the OE CD-ROM) can be booted to ISL and used to load and run offline diagnostics.
Required and Recommended Patches
No patches are required for the HP-UX 11i. initial release.
CAUTION: Info Tool Causes 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).
The root cause is a problem in the HP-UX 11i kernel, which is exposed when the Info Tool is run as described above. To correct the problem and avoid potential HPMCs, load patch PHKL_25552 or its successor. This is a kernel patch and requires a system reboot.
STM only exposes this problem 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.
CAUTION: Monitoring Changes for disc30, sdisk and disk array devicesAs 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 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.11.03Support Tools and the EMS hardware monitors are not affected. For complete information, see EMS Incompatibility Problem.
If you wish to remove the STM online diagnostic system after it has already been installed, type:

EMS Hardware Monitors
- Once you install a specific stream (e.g. HP-UX 111i), 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- 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:- 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.
- On the Instant Information CD-ROM.
Distributed with the hardware support tools (diagnostics) are the EMS Hardware Monitors, an important tool for maintaining system availability. The EMS 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 February 1999 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.
For complete information on installing and using EMS hardware event monitors, as well as a list of supported hardware, refer to the documents listed in "Getting More Information" earlier in this file.
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.
- Written to /var/adm/syslog/syslog.log
- Sent to EMAIL address root
To configure, enable, or disable hardware event monitoring, run the monitoring request manager: /etc/opt/resmon/lbin/monconfig .
