When AC cycling a SPARC T8 system, it is possible that the Service Processor configuration will be reset to factory defaults. If this occurs, the Service Processor date and time will be set to Jan 1 00:00:00 1970, and you will see the following output from the Service Processor serial port while the Service Processor is booting after the AC power cycle:

Workaround
There is no workaround for this issue. However, follow best practices and perform accurate backups of the Oracle ILOM configuration and your LDOMs configuration before AC power cycling the system. This will ease recovery if this situation occurs.
Recovery
Restore the Oracle ILOM configuration and LDOMs configuration from backups. To restore your Oracle ILOM Configuration, see: Backing Up, Restoring, or Resetting the Oracle ILOM Configuration. To restore your LDOMs configuration, see: Restoring Domain Configurations.
