Automatic System Recovery
The system provides for Automatic System Recovery (ASR) from failures in memory
modules or PCI cards.
Automatic System Recovery functionality enables the system to resume operation
after experiencing certain nonfatal hardware faults or failures. When ASR is enabled,
the system’s firmware diagnostics automatically detect failed hardware components.
An autoconfiguring capability designed into the system firmware enables the system
to unconfigure failed components and to restore system operation. As long as the
system is capable of operating without the failed component, the ASR features enable
the system to reboot automatically, without operator intervention.
Note – ASR is not activated until you enable it. See “Enable ASR” on page 47.
For more information about ASR, refer to the service manual for your server.
