You should review the MP logs for a message related to disabled CPU or even do a "info all" from EFI shell.

Since you state the that system rebooted unexpectedly and you confirmed that a CPU is deconfigured, I would suspect that CPU as faulty and would not advise you to configure it again (unless you want another crash).

Likely there is an mca entry under /var/tombstones with the date and time of the reboot. If you have a support contract with HP, send them this data to have it confirmed if you like.
