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.
