Questions to Consider

Before troubleshooting any system problem, first check the site
maintenance log for the system's service history.
Be sure to ask the system manager the following questions:
•
Has the system been used and did it work correctly?
•
Have changes to hardware or updates to firmware or software been made to
the system recently? If so, are the revision numbers compatible for the
system? (Refer to the system release notes.)
•
What is the current state of the system?
If the operating system is down, but you are able to access the SRM
console, use the console environment diagnostic tools, including the
OCP display, power-up display, and SRM commands.
If you are unable to access the SRM console, enter the RMC CLI and
issue commands to determine the hardware status. See Chapter 7.
If the operating system has crashed and rebooted, the CCAT (Compaq
Crash Analysis Tool), the Compaq Analyze service tools (to interpret
error logs), the SRM crash command, and operating system exercisers
can be used to diagnose system problems.
