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 78
)," 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 80
)." 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.
