ESD wrist strap, and software utilities, necessary to troubleshoot the
problem.
HP recommends you have access to the server documentation for server-
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:
