If the operating system cannot be booted, then use the offline support tools to help resolve the
issue. The offline support tools are available either from the UEFI partition, or from the IPF Offline
Diagnostics and Utilities CD (IPF systems only). After the issue preventing booting has been resolved,
boot the operating system, and then use the online support tools for any further testing.
If you cannot reach UEFI from either the main disk or from a CD, you must troubleshoot, using the
visual fault indicators, console messages, and system error logs that are available.
Online diagnostics and exercisers
Online support tools are available which permit centralized error archiving, and which provide
hardware inventory tools, as long as the agents/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
the HP-UX 11.23 and greater operating systems, include the WBEM features added by
SysFaultMgmt.
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 CRUs.
Exercisers stress devices in order to facilitate the reproduction of intermittent issues.
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.
Online support tools list
The following online support tools are available on HP-UX 11.31 hosted systems. In some cases,
a tool, such as a disk exerciser, is generic to many types of hardware; in other cases, a tool, such
as a tape diagnostic. is specific to a particular technology or type of tape drive.
