Troubleshooting
This appendix includes the following topics:
•
When the Server Does Not Start
You are provided with initial instructions on what to try and where to go for help
for the most common problems encountered during the initial Power-On
Self-Test (POST). A successful startup requires the server to complete this test
each time you power up, before the server can load the operating system and start
running software applications.
•
Diagnostic Steps
If the server does not power up after you have performed initial troubleshooting
procedures, use the tables in this section to identify possible reasons for the
problem, possible solutions, and references to other sources of information.
•
Problems After Initial Boot
Once the server has passed the POST, you may still encounter errors, such as an
inability to load your operating system. You are provided with instructions on
what to try and where to go for help when you encounter errors after the server
completes the POST.
•
ROMPaq Disaster Recovery
During troubleshooting, it may become apparent that your system ROM is
corrupted. Because the server has redundant ROM capability, you can use the
backup ROM until it is feasible to bring the server down. If both ROMs are
corrupted, you will need to perform the ROMPaq disaster recovery procedure
before the server will boot.
•
Other Information Resources
This section provides a list of reference information available for the server.
For troubleshooting information beyond the scope of this guide, both general and
specific to the servers, refer to Table D-8.
