Compaq Diagnostics Utility

Automatic Server Recovery-2

Power-On Self-Test

The Compaq Diagnostics Utility tests the operation of your Compaq hardware
and isolates failed parts, whenever possible. Diagnostic error codes are
generated when the Diagnostics Utility recognizes a problem. These error
codes help identify defective components. A Diagnostics diskette can be made
by running the Compaq Server Diagnostics file available for download from
the following website:

ASR-2 is a feature of ProLiant servers that resets the system in the event of a
catastrophic operating system error like a blue-screen, ABEND (abnormal
end), or panic. A system failsafe timer, the ASR-2 timer, is started when the
Compaq System Management driver, also known as the health driver, is
loaded. The timer is reset periodically during normal operation, but in the
event of operating system failure, the timer expires and restarts the server.
ASR-2 increases server up time by restarting the server within a predetermined
amount of time after the system stops responding. The Compaq Insight
Manager console notifies you in the event of an ASR-2 restart. You can
disable ASR-2 from the Compaq Insight Manager console.
POST is a series of diagnostic tests that checks firmware and assemblies to
ensure that the system is functioning properly. This utility runs automatically
every time the server is powered up.
See Appendix D, "Troubleshooting," for the normal power-up sequence and
diagnosis of problems encountered during POST.
