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
hardware and operating system release notes).
•
What is the state of the system? Is the operating system running?
•
If the operating system is down and you are not able to bring it up, use the diagnostic
beep codes and console environment diagnostic tools, such as the power-up display on
the VGA terminal and ROM-based diagnostics (RBDs).
If the operating system is running, use the operating system environment diagnostic tools,
such as the DEC VET exerciser.
