The diagnostics software, which is installed with HP-UX 11i v3, consists of two product bundles:

  • OnlineDiag

  • SysFaultMgmt

These bundles include many tools to help verify, troubleshoot, and monitor PA-RISC and Itanium-based system hardware such as processors, memory, power supplies, fans, interface cards and mass storage devices.

The OnlineDiag bundle includes the following tools:

  • Support Tools Manager (STM)

    STM provides access to a complete set of support tools for use in verifying and troubleshooting system hardware. STM also provides a a set of daemons that proactively monitor the system for errors. This information is used by the EMS Hardware Monitors.

  • EMS Hardware Monitors

    EMS hardware monitors help detect unusual activities, such as events, occurring on various hardware resources, thereby preventing hardware failure. Monitors also provide information about events that provide recommended solutions to hardware.

The SysFaultMgmt bundle includes the System Fault Management (SFM) software. The SFM software includes the following tools:

  • SFM Providers

    SFM monitors the health of HP servers and retrieves information about hardware such as memory, processors, power supplies, and cooling devices. SFM operates in the Web-based Enterprise Management (WBEM) environment.

  • EVWEB

    EVWEB is packaged with SFM and can be used to view and administer WBEM indications generated on the HP-UX 11i v3 system.

  • EMT

    EMT enables you to view most errors that can occur on HP-UX 11i v3 systems. It also provides probable cause for errors, and recommended actions.

CAUTION: Removing the OnlineDiag bundle or the SysFaultMgmt bundle, or both, prevents products with dependencies on the diagnostics from functioning correctly. If the OnlineDiag bundle or the SysFaultMgmt bundle are not installed, protections from some hardware failures are removed. Without these bundles installed on your system, it is much harder to troubleshoot and fix problems when a hardware failure occurs. To ensure the reliability of your computer system, HP highly recommends that you install the OnlineDiag and SysFaultMgmt bundles with HP-UX 11i v3. With a media install, the OnlineDiag and SysFaultMgmt bundles are installed by default with any HP-UX 11i Operating Environment.

The following lists the uses of tools contained in OnlineDiag and SysFaultMgmt bundles:

  • Protects your system from hardware failures, for example, memory problems.

  • Includes EMS Hardware Monitors that notifies you of hardware events.

  • Maintains logs that help you determine the cause of failures.

  • Enables you to troubleshoot system problems with the system online.

Starting with the HP-UX 11i v3 March 2008 release, upon a successful OE upgrade, SFM is the default monitoring system for monitoring the core hardware components. Online Diagnostics, which is included in the OnlineDiag bundle, is shut down as soon as an OE upgrade is initiated. Upon the successful completion of the OE upgrade, SFM is the default monitoring system. However, STM, which is included in the OnlineDiag bundle, restarts and continues to function properly.

The SFMIndicationProvider, which is included in the SysFaultMgmt bundle, replaces certain EMS Hardware Monitors. However, you can continue to receive all the events from the remaining EMS Hardware Monitors through the EMS framework. Indications generated by the SFMIndicationProvider can be directed to the EMS framework through the WBEM Wrapper Monitor. For information on the monitors that the SFMIndicationProvider replaces, and for instructions on how to switch to the EMS monitoring mode, see the SFM Release Notes available at:

http://docs.hp.com/en/diag.html

NOTE: You can continue to receive all the events from the remaining EMS Hardware Monitors through the EMS framework. Indications generated by the SFMIndicationProvider can be directed to the EMS framework through the WBEM Wrapper Monitor.

To switch to Online Diagnostics for monitoring the core hardware components, you must switch from the SFM mode to the EMS mode. To switch to the EMS mode, enter the following command at the HP-UX prompt:

# /opt/sfm/bin/sfmconfig -w -e

For more information about the sfmconfig command, see sfmconfig(1).

For more information on SFMIndicationProvider, see the SFM Administrator's and User's Guide at:

On most systems, no special configuration of Online Diagnostics is necessary. For complete information, see the Online Diagnostics Administrator's Guide available at:
