Diagnostic Tools 3-61 Compaq Health Driver IMPORTANT: Before configuring ASR-2, verify that the System Configuration Utility and Diagnostics software are installed on the system partition. ASR-2 must have this software to start Compaq utilities after a system restart. Compaq recommends using this software even if you configure ASR-2 to start the operating system. 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 five minutes reduces server downtime and allows the server to recover quickly. For local (attended) servers located onsite, you can set the software error recovery timeout for 20 or 30 minutes, giving you time to arrive at the server if you want to manually diagnose the problem. The Compaq Health Driver is independent of the ASR-2 timer. Load the driver and enable the ASR-2 timer. To allow the driver to detect and log information about numerous hardware and software errors in the IML. 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 Critical Error Log or the IML, depending on the server support. This information can be used to diagnose an operating system crash or server lockup, while still allowing the server to be restarted.

software are installed on the system partition. ASR-2 must have this software to start Compaq utilities
after a system restart. Compaq recommends using this software even if you configure ASR-2 to start the
operating system.
The Compaq Health Driver continually resets the ASR-2 timer according to the frequency you

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

The Compaq Health Driver is independent of the ASR-2 timer. Load the driver and enable the
