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

i performed the follwing command in MP console and the out put as follows

 MP:CM> ss


SS
System Processor Status:
   Monarch Processor: 0
    Processor Module 0: Installed and Configured     Processor Module 1: Installed and Configured     Processor Module 2: Installed and NOT CONFIGURED     Processor Module 3: Installed and Configured

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.
