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.
