The ASR-2 feature depends on the application and driver that routinely notify
the ASR-2 hardware that the system is operating properly. If the time between
ASR-2 notifications by the application and driver exceeds the specified time
period, ASR-2 assumes a fault has occurred and initiates the recovery process.
The available recovery features are as follows:
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
Processor Recovery – automatically reconfigures the server to operate
without removing a processor board that has failed after an ASR
restart.
Unattended Recovery
For unattended recovery, ASR-2 logs the error information to the Critical
Error Log, resets the server, pages you (if a modem is present and you
selected paging), and tries to restart operating system. Often the server restarts
successfully, making unattended recovery the ideal choice for remote
locations where trained service personnel are not immediately available.
