User Service Guide, Third Edition - HP Integrity rx4640 Server

is already running, it is best not to shut it down. To resolve problems, 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 the 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 want 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 11.23 hosted servers. 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.
