Determine if the Drive Backplane Is Faulty

You must determine if the drive backplane is faulty before you replace it.

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

   See Front Panel Components (Service).

2. In Oracle ILOM, check the health of the storage system.

   -> show /System/Storage 
    /System/Power
    	Targets:
    		Disks
    		Controllers
    		Volumes
    		Expanders
    	Properties:
    		health = OK
    		health_details = -
   ...
   ->

3. Verify that the drive backplane is faulty.

   For example, type:

   -> show faulty
   Target              | Property               | Value
   --------------------+------------------------+-------------------------------
   /SP/faultmgmt/0     | fru                    | /SYS/DBP
   ...
   ->

   • If the drive backplane is faulty, you will see /SYS/DBP under the Value heading.

   • If a FRU value different from /SYS/DBP is displayed, see Component Service Task Reference to identify which component is faulty.

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

   See Identify Faulted Components.

   Check the Fault class and Description fields for more information.

5. If the drive backplane is faulty, replace it.

   See Remove the Drive Backplane.

6. If you are unable to determine if the drive backplane is faulty, seek more information.

   See Detecting and Managing Faults.
