Locate a Faulty CPU

1. Check to see if any System Service Required LEDs are lit or flashing.

   See Interpreting Diagnostic LEDs.

2. In Oracle ILOM, check the health of the CPUs.

   Replace x with 0 or 1 in the dual-processor configuration. The CPU is always CPU_0 in the single-processor configuration.

   -> show /System/Processors/CPUs/CPU_x
    /System/Processors/CPUs/CPU_0
    	Targets:
    	Properties:
    		health = Service Required

3. Run the show faulty command.

   See Display Faults (show faulty Command).

4. Use the Oracle ILOM faultmgmt shell to identify the faulty component.

   See Display Faults (faultmgmt Shell).

5. Run UEFI CPU diagnostics.

   Refer to the Oracle x86 Servers Diagnostics, Applications, and Utilities Guide for Servers with Oracle ILOM 3.1 and Oracle ILOM 3.2.x at http://www.oracle.com/goto/x86AdminDiag/docs for information.

6. If you are unable to determine if a CPU is faulty, seek further information.

   See Detecting and Managing Faults.
