Diagnostics
A suite of offline and online support tools are available to enable manufacturing, field support personnel, and
you to troubleshoot server problems. In general, if the operating system (HP-UX) is already running, it is best
not to shut it down. Use the online support tools.
If the OS cannot be booted, use the offline support tools to resolve the problem. The offline support tools are
available from the EFI partition. Once you resolve the problem preventing booting, boot HP-UX, and use the
online support tools for any further testing.
If it is not possible to reach the EFI from either the main disk or from LAN, you must troubleshoot, using the
visual fault indicators, console messages, and system error logs that are available.

Online Diagnostics/Exercisers

Online support tools are provided under both operating systems. Centralized error archiving and hardware
inventory tools for both OSes are available as long as the agents/providers that support them are installed on
the managed server.
On HP-UX systems, the legacy tools within OnlineDiag continue to be supported. The online support tools, on
HP-UX 11.23 and greater, include the Support Tool Manager (STM) tools, and the additional Web-Based
Enterprise Management (WBEM) features added by SysFaultMgmt.
The STM suite of tools includes verifiers, diagnostics, exercisers, information modules, and expert tools.
Verifiers quickly determine whether or not a specific device is operational by performing tasks similar in
nature to the way applications use the device. No license is required to run the verifiers.
Diagnostics are tools designed to identify faulty or failed FRUs.
Exercisers stress devices in order to facilitate the reproduction of intermittent problems.
Information modules create a log of information specific to one device, including:
• The product identifier
• A description of the device
• The hardware path to the device
• The vendor
• Onboard log information (if applicable)
• Miscellaneous information associated with the device
• The firmware revision code, if firmware is present in the device, is also displayed
Expert tools are device-specific troubleshooting utilities for use by sophisticated users. Their functionality
varies from tool to tool, but they are intended to be interactive, and rely on users to provide information
necessary to perform a particular task. These tools require users to have the appropriate license, if they wish
to run them.
Online Support Tool Availability
Online diagnostics are included in the HP-UX OE media, and are installed by default.
