In addition to the front panel diagnostic LEDs, CRUs provide additional diagnostic LEDs. CRU LED order and layout is product dependent.

NOTE: If multiple error conditions occur, all applicable CRU lights activate. The most critical error determines the front panel LED state.

Diagnostics

A suite of offline and online support tools are available to help you to troubleshoot system problems. If the OS is already running, use the online support tools.

If the OS cannot be booted, use the offline support tools. If possible, shut down the OS only when online troubleshooting fails. The offline support tools are available either from the EFI partition or from the IPF offline Diagnostics and Utilities CD (IPF systems only). Once the problem preventing booting has been resolved, boot the OS; use the online support tools for any further testing.

If you cannot reach the EFI from either the main disk or from a CD, use the visual fault indicators, console messages, and system error logs to troubleshoot the problem.

Online Diagnostics and Exercisers

Online support tools enable centralized error archiving and hardware inventory, as long as the agents or providers that support them are installed on the managed server.

On HP-UX systems, the legacy tools within OnlineDiag are supported. The online support tools on HP-UX 11i v2, include the Support Tool Manager (STM) tools and the Web-Based Enterprise Management (WBEM) features added by SysFaultMgmt.

The STM suite of tools includes the following:

Information Information modules create a log of information specific to one device, including:

 

Product identifier

 

• Description of the device

 

• Hardware path to the device

 

Vendor

 

• Onboard log information (if applicable)

 

• Miscellaneous information associated with the device

 

• The firmware revision code, if firmware is present in the device

Verifiers

Verifiers quickly determine whether or not a specific device is working by

 

performing tasks similar to those that the applications perform using the

 

device. No license is required to run the verifiers.

Exercisers

Exercisers stress devices to facilitate the reproduction of intermittent

 

problems.

Diagnostics

Diagnostics are tools designed to identify faulty or failed FRUs.

Expert Tools

Expert tools are device-specific troubleshooting utilities for use by expert

 

administrators only. Their functionality varies from tool to tool, but they are

 

intended to be interactive, and rely on the administrator to provide
