Online Diagnostics

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.

On most systems, no special configuration of Online Diagnostics is necessary. For complete information, refer to the diagnostics products documents available at:
