ESD wrist strap, and software utilities, necessary to troubleshoot the
problem.

specific information.

Symptom information

Before troubleshooting a server problem, collect the following information:
•
What events preceded the failure? After which steps does the problem occur?
•
What has been changed between the time the server was working and now?
•
Did you recently add or remove hardware or software? If so, did you
remember to change the appropriate settings in the server setup utility, if
necessary?
•
Has the server exhibited problem symptoms for a period of time?
•
If the problem occurs randomly, what is the duration or frequency?
To answer these questions, the following information may be useful:
•
Run HP Insight Diagnostics (on page 22) and use the survey page to view the
current configuration or to compare it to previous configurations.
•
Refer to your hardware and software records for information.

Diagnostic steps

To effectively troubleshoot a problem, HP recommends that you start with the
first flowchart in this section, "Start diagnosis flowchart (on page 30)," 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 32)." 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.
The available flowcharts include:
