Troubleshooting resources
The HP ProLiant Servers Troubleshooting Guide provides simple procedures for resolving common
problems as well as a comprehensive course of action for fault isolation and identification, error message
interpretation, issue resolution, and software maintenance.
To obtain the guide, refer to any of the following sources and then select the HP ProLiant Servers
Troubleshooting Guide:
• The server-specific Documentation CD
• The Business Support Center on the HP website ( http://www.hp.com/support ). Navigate to the
server technical support page. Under self-help resources, select ProLiant Troubleshooting
Guide.
• The Technical Documentation website ( http://www.docs.hp.com ). Select Enterprise Servers,
Workstations and Systems Hardware, and then the appropriate server.
Server diagnostic steps
This section covers the steps to take in order to diagnose a problem quickly.
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page
93 )," and follow the appropriate diagnostic path. If the other
flowcharts do not provide a troubleshooting solution, follow the diagnostic steps in "General diagnosis
flowchart (on page
94 )." The General diagnosis flowchart is a generic troubleshooting process to be used
when the problem is not server-specific or is not easily categorized into the other flowcharts.
IMPORTANT: This guide provides information for multiple servers. Some information may not apply to the
server you are troubleshooting. Refer to the server documentation for information on procedures, hardware
options, software tools, and operating systems supported by the server.
WARNING: To avoid potential problems, ALWAYS read the warnings and cautionary
information in the server documentation before removing, replacing, reseating, or
modifying system components.
