Introduction to Troubleshooting
To troubleshoot your system, you must be familiar with the HP-UX and Linux®
operating systems and be able to start and stop processes. You should also be familiar
with the Offline Diagnostics Environment and the Support Tools Manager for HP-UX
systems.
First note any event messages, and use the diagnostics tool that is appropriate for your
system to determine what failed. Note that event messages can be found in Appendix C
of this document. If a test fails, the diagnostics message will give you an indication of the
Field Replaceable Unit (FRU) to replace.
