Diagnostics and Troubleshooting 3-51 Compaq Integrated Remote Console The standard Compaq Integrated Remote Console performs a wide range of configuration activities. The console Is accessible with an ANSI terminal Operates independently of the operating system Provides for remote server reboot Provides access to system configuration Uses out-of-band communication with a dedicated management modem installed in the server For more information, see the Integrated Remote Console User Guide that shipped with the server. IMPORTANT: Before configuring ASR-2, verify that the System Configuration Utility and Diagnostics software are installed on the system partition. ASR-2 must have these to start Compaq Utilities after a system restart. Compaq recommends these even if you configure ASR-2 to start the operating system. 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 reset, because of 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 time-out for 5 minutes reduces server downtime and enables the server to recover quickly. For local, attended servers onsite, you can set the software error recovery time-out for 20 or 30 minutes, giving you time to arrive at the server to 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 about 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 Critical Error Log or the IML, depending on the server support. The information can be used to diagnose an operating system crash or server lock-up while still enabling the server to be restarted.

Before configuring ASR-2, verify that the System Configuration Utility and Diagnostics
software are installed on the system partition. ASR-2 must have these to start Compaq Utilities after a

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 reset, because of 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 time-out for
5 minutes reduces server downtime and enables the server to recover quickly. For local,
attended servers onsite, you can set the software error recovery time-out for 20 or 30 minutes,

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 about
numerous hardware and software errors. However, you cannot enable the ASR-2 timer without
