Troubleshooting 57
CAUTION:
The server is designed to be electrically grounded (earthed). To ensure proper
operation, plug the AC power cord into a properly grounded AC outlet only.
Preparing the server for diagnosis
1.
Be sure the server is in the proper operating environment with adequate power, air conditioning, and
humidity control. Refer to the server documentation for required environmental conditions.
2.
Record any error messages displayed by the system.
3.
Remove all diskettes and CDs from the media drives.
4.
Power down the server and peripheral devices if you will be diagnosing the server offline. Always
perform an orderly shutdown, if possible. This means you must:
a.
Exit any applications.
b.
Exit the operating system.
c.
Power down the server (on page
15
).
5.
Disconnect any peripheral devices not required for testing (any devices not necessary to power up the
server). Do not disconnect the printer if you want to use it to print error messages.
6.
Collect all tools and utilities, such as a Torx screwdriver, loopback adapters, 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 since the time the server was working?
•
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?
•
How long has the server exhibited problem symptoms?
•
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
51
) 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.
•
Refer to server LEDs and their statuses.
Diagnostic steps
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page
58
)," 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
59
)." 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.
