Additional information

The Baseboard Management Controller (BMC) version 1.02 and higher addressed an issue where CPU mis-match caused inconsistent results. The BMC itself cannot alleviate the Symptom, but it can provide information about the root cause.

This Symptom may be caused by a mismatch of the CPUs installed in the blade. The BMC software will be updated to read information from the PSOC, which indicates the compatibility of the processors, and generates an alarm if the configuration is incorrect.
