Automatic System Recovery
Automatic system recovery (ASR) functionality enables the system to resume
operation after experiencing certain non-fatal hardware faults or failures. Once you
enable ASR, the system’s diagnostic firmware automatically detects failed hardware
components. The autoconfiguring capability designed into the system firmware
enables the system to unconfigure failed components and 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.
The system provides ASR for failures in CPU cores or threads, memory modules, and
PCIE slots.
