Compaq ProLiant ML530 Servers Maintenance and Service Guide
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 IML, 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.
Attended Recovery
For attended 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)
■
Starts Compaq Utilities from the hard drive
■
Enables remote access
During system configuration, these utilities are placed on the system utilities partition of the
hard drive.
If your system is configured for dial-in access and you have a modem with an auto-answer
feature installed, you can dial in and remotely diagnose or reconfigure the server.
If you have configured the Compaq Utilities for network access, you can access the utilities over
the network. You can use Compaq Insight Manager for dial-in or network access.
