Fault Management Overview
The goal of fault management and monitoring is to increase server 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 problems automatically, as close as possible to the time of occurrence.
• To diagnose problems automatically, at the time of detection.
• To automatically report (in understandable text) a description of the problem, the likely
cause(s) of the problem, the recommended action(s) to resolve the problem, and detailed
information about the problem.
• To ensure 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 SysFaultMgmt WBEM
indication providers, as well as by the Event Management Service (EMS). The Event Management
Service and WBEM provide frameworks for monitoring and reporting events.
SysFaultMgmt WBEM indication providers and the EMS Hardware Monitors 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 operation or cause data loss.
Complete information on installing and using EMS hardware event monitors, as well as a list of
supported hardware, can be found in the EMS Hardware Monitors Users Guide. An electronic copy
of this book is provided on the HP website at:http://docs.hp.com/hpux/diag.
WBEM Indication Providers and EMS Hardware Monitors
Hardware monitors are available to monitor the following components (these monitors are
distributed free on the OE media):
• Chassis/Fans/Environment
• CPU monitor
• UPS monitor
• FC Hub monitor
• FC Switch monitor
• Memory monitor
• Core Electronics Components
• Disk drives
• Ha_disk_array
Troubleshooting Using Online Support Tools
Online Diagnostics/Exercisers
Online support tools are provided under both operating systems. Centralized error archiving
and hardware inventory tools for both operating system 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.
