To use this feature, you must use the System Configuration Utility to install Compaq Utilities in the system partition. You can enable the ASR-2 feature to restart a server after a critical hardware or software error occurs. If a critical error occurs, the server records the error information in the Integrated Management Log, restarts the system, and pages you. Using the Compaq System Configuration Utility, configure the system for automatic recovery or for attended local or remote access to diagnostic and configuration tools. NOTE: ASR-2 is available only on operating systems using the ASR-2 drivers provided by Compaq. You can also configure ASR-2 to page an administrator when the system restarts. ASR-2 depends on the application and driver that routinely notify the ASR-2 hardware of proper system operations. If the time between ASR-2 notifications exceeds the specified period, ASR-2 assumes a fault has occurred and initiates the recovery process. To configure ASR-2: 1. Run the System Configuration Utility. 2. Select View and Edit Details. 3. Set the software error recovery status to Enabled. 4. Set the software error recovery timeout. The available recovery features are: I Software Error Recovery-automatically restarts the server after a software-induced server failure I Environmental Recovery-allows the server to restart when temperature, fan, or AC power conditions return to normal Unattended Recovery For unattended recovery, ASR-2 performs the following actions: I Logs the error information to the IML I Resets the server I Pages you (if a modem is present and you selected Paging) I Tries to restart the operating system Often the server restarts successfully, making unattended recovery the ideal choice for remote locations where trained service personnel are not immediately available. If ASR-2 cannot restart the server within 10 attempts, it places a critical error in the Integrated Management Log, starts the server into Compaq utilities, and enables remote access (if you configured remote access). To use this level of ASR-2, you must configure ASR-2 to load the operating system after restart.

Compaq ProLiant 8500 Server Maintenance and Service Guide
Automatic Server Recovery-2
Automatic Server Recovery-2 (ASR-2) lets the server restart automatically from the operating
system or the Compaq Utilities. To use this feature, you must use the System Configuration
Utility to install Compaq Utilities in the system partition.
You can enable the ASR-2 feature to restart a server after a critical hardware or software error
occurs. If a critical error occurs, the server records the error information in the Integrated
Management Log, restarts the system, and pages you. Using the Compaq System Configuration
Utility, configure the system for automatic recovery or for attended local or remote access to
diagnostic and configuration tools.
NOTE:
ASR-2 is available only on operating systems using the ASR-2 drivers provided by Compaq.
You can also configure ASR-2 to page an administrator when the system restarts. ASR-2
depends on the application and driver that routinely notify the ASR-2 hardware of proper
system operations. If the time between ASR-2 notifications exceeds the specified period, ASR-2
assumes a fault has occurred and initiates the recovery process.
To configure ASR-2:
1.
Run the System Configuration Utility.
2.
Select View and Edit Details.
3.
Set the software error recovery status to Enabled.
4.
Set the software error recovery timeout.
The available recovery features are:
■
Software Error Recovery
—
automatically restarts the server after a software-induced
server failure
■
Environmental Recovery
—
allows the server to restart when temperature, fan, or
AC power conditions return to normal
Unattended Recovery
For unattended recovery, ASR-2 performs the following actions:
■
Logs the error information to the IML
■
Resets the server
■
Pages you (if a modem is present and you selected Paging)
■
Tries to restart the operating system
Often the server restarts successfully, making unattended recovery the ideal choice for remote
locations where trained service personnel are not immediately available.
If ASR-2 cannot restart the server within 10 attempts, it places a critical error in the Integrated
Management Log, starts the server into Compaq utilities, and enables remote access (if you
configured remote access).
To use this level of ASR-2, you must configure ASR-2 to load the operating system after restart.
