Table 1–5 Diagnostic Flow for Errors Reported by the Operating System
Symptom Action
System is hung or has crashed. Examine the crash dump file.
Refer to OpenVMS AXP Alpha System Dump Analyzer
Utility Manual for information on how to interpret
OpenVMS crash dump files.
Refer to the Guide to Kernel Debugging (AA–PS2TA–
TE) for information on using the DEC OSF/1 Krash
Utility.
Errors have been logged and the
operating system is up.
Examine the operating system error log files to isolate
the problem.
If the problem occurs intermittently, run an operating
system exerciser, such as DEC VET, to stress the
system.
Refer to the DEC Verifier and Exerciser Tool User’s
Guide (AA–PTTMA–TE) for instructions on running
DEC VET.
1.2 Service Tools and Utilities
This section lists the array of service tools and utilities available for acceptance
testing, diagnosis, and serviceability and provides recommendations for their use.
Error Handling/Logging
DEC OSF/1, OpenVMS, and Microsoft Windows NT operating systems provide
recovery from errors, fault handling, and event logging. The DECevent
Translation and Reporting Utility for OpenVMS and Error Report Formatter
(ERF) provides bit-to-text translation of event logs for interpretation. DEC
OSF/1 uses uerf to present the same kinds of information.
RECOMMENDED USE: Analysis of error logs is the primary method of
diagnosis and fault isolation. If the system is up, or you are able to bring it
up, look at this information first.
ROM-Based Diagnostics (RBDs)
Many ROM-based diagnostics and exercisers are embedded in AlphaServer
1000 systems. ROM-based diagnostics execute automatically at power-up and
can be invoked in console mode using console commands.
