Diagnostics

A suite of offline and online support tools are available to enable troubleshooting server blade issues. In
general, if the operating system (HP-UX) is already running, Hewlett Packard Enterprise does not
recommend shutting down the server blade. Use the online support tools.
If the OS cannot be booted, use the offline support tools to resolve the issue. The offline support tools are
available from the UEFI partition. after you resolve the issue preventing booting, boot HP-UX, and use the
online support tools for any further testing.
If it is not possible to reach the UEFI 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.

Fault management overview

The goal of fault management and monitoring is to increase server blade availability, by moving from a
reactive fault detection, diagnosis, and repair strategy to a proactive fault detection, diagnosis, and repair
strategy. The objectives are:
• To detect issues automatically, as close as possible to the time of occurrence.
• To diagnose issues automatically, at the time of detection.
• To automatically report (in understandable text) a description of the issue, the likely causes of the
issue, the recommended actions to resolve the issue, and detailed information about the issue.
• To be sure that tools are available to repair or recover from the fault.

HP-UX Fault management

Proactive fault prediction and notification is provided on HP-UX by SFM and WBEM indications. WBEM is
a collection of standards that aid large-scale systems management. WBEM allows management
applications to monitor systems in a network.
SFM and WBEM indication providers enable users to monitor the operation of a wide variety of hardware
products, and alert them immediately if any failure or other unusual event occurs. By using hardware
event monitoring, users can virtually eliminate undetected hardware failures that could interrupt server
blade operation or cause data loss.
