Zusammenfassung:A system, method, and computer program product are disclosed for preventing machine crashes due to hard errors in one of multiple, different processors that are included in a logically partitioned data processing system. An error occurring in one of the processors is detected. A determination is then made regarding whether the processor has been deconfigured. The partition is then rebooted only in response to a determination that the processor has been deconfigured and will not be included in the partition processor resources. Thus, only the configured processors are rebooted. The deconfigured processor is not rebooted.
