Automatic Server Recovery - HP ProLiant WS460c Gen9 Maintenance And Service Manual

Automatic Server Recovery

ASR is a feature that causes the system to restart when a catastrophic operating system error occurs,
such as a blue screen, ABEND (does not apply to HPE ProLiant DL980 Servers), or panic. A system
fail-safe timer, the ASR timer, starts when the System Management driver, also known as the Health
Driver, is loaded. When the operating system is functioning properly, the system periodically resets the
timer. However, when the operating system fails, the timer expires and restarts the server.
ASR increases server availability by restarting the server within a specified time after a system hang. At
the same time, the SIM console notifies you by sending a message to a designated pager number that
ASR has restarted the system. You can disable ASR from the System Management Homepage or
through RBSU.
