Compaq Health Driver
The Compaq Health Driver continually resets the ASR-2 timer according to the frequency
you specified in the System Configuration Utility (for example, 10 minutes). If the ASR-2
timer counts down to zero before being reset, due to an operating system crash or a server
lockup, ASR-2 restarts the server into either Compaq Utilities or the operating system (as
indicated by the System Configuration parameters). The default value is 10 minutes. The
allowable settings are 5, 10, 20, and 30 minutes.
For remote and off-site (unattended) servers, setting the software error recovery timeout for
5 minutes reduces server downtime and allows the server to recover quickly. For local
(attended) servers located on site, you can set the software error recovery timeout for
20 or 30 minutes, giving you time to arrive at the server if you wish to manually diagnose the
problem.
The Compaq Health Driver is independent of the ASR-2 timer. You should load it and enable
the ASR-2 timer. This allows the driver to detect and log information in the IML regarding
numerous hardware and software errors. However, you cannot enable the ASR-2 timer
without loading the Compaq Health Driver.
Before ASR-2 restarts the server, it records any information available about the condition of
the operating system in the IML This information can be used to diagnose an operating
system crash or server lock-up, while still allowing the server to be restarted.
