FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW:

What: A DIMM in a MaxRep3 Engine has failed and needs to be replaced.

Where: See "show /System/Open_Problems output from ILOM. 

Why: A MaxRep3 Engine DIMM has failed.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?

The MaxRep3 Engine with the DIMM failure will have a warning status in the Oracle FS System Manager GUI.  This procedure requires that the MaxRep3 Engine be powered off.

To familiarize yourself with the procedure in general, a video of the basic procedure can also be found here.  It should not be viewed as a substitute for the instructions below.

QRC for this procedure:

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

1. Prepare the MaxRep3 Engine for Service Procedure.
1. Using the ILOM Interface, confirm the failed part and location:
• Browser: point a browser at the ILOM IP address and select Open Problems in the navigation tree on the left.
• CLI: ssh to ILOM IP address and execute "show /System/Open_Problems"
2. Disable Call-Home to prevent spurious alerts (see <Document 1942676.1> FS System: How to disable Call Home to prevent Automatic Service Request ASR Generation).
3. Shutdown the MaxRep3 Engine (see <Document 2066803.1> MaxRep: How to Perform a Graceful Shutdown of the Oracle MaxRep3 Engine).
4. Use ESD precautions.
   
   
2. Access the failed DIMM:
1. Deploy the anti-tip legs in the front of the rack.
2. Slide the MaxRep3 Engine into the service position.
3. Unplug both power cords.
4. Loosen the two captive screws in the rear of the top cover.
5. Slide the top cover back and remove.
6. Unplug the cables connected to the Drive Compartment - suggest they be labeled to make reconnections easier.
7. Loosen the four captive screws that secure the Drive Compartment to the MaxRep3 Engine chassis and lift it into the service position.
8. Remove the clear plastic Air Duct.
9. Use the Fault Remind button (located between the power supply and the first riser) to confirm the location of the failed DIMM.
10. Press the release tabs on both ends of the DIMM to remove it.
    
    
3. Install the replacement DIMM and reassemble:
1. Insert the replacement DIMM into the slot evenly until the release tabs lock it into place.
2. Reinstall the clear plastic Air Duct.
3. Lower the Drive Compartment and secure the four captive screws.
4. Reconnect the cabling to the Drive Compartment.
5. Close the top cover being certain to catch the mushroom tabs in the front to secure it.  Failure to do so will inhibit the MaxRep3 Engine from being slid back into the rack.
6. Tighten the two screws in the rear.
   
   
4. Return to operation.
1. Plug in both power cords.
2. Return the MaxRep3 Engine to the rack position.
3. Return the anti-tip legs to their normal position.
   
   
5. Log into the ILOM to confirm the fault has cleared.
   
   1.  Start Fault Management Shell:
      
      ->start /SP/faultmgmt/shell
      Are you sure you want to start /SP/faultmgmt/shell (y/n)? y
      
      faultmgmtsp>
       
   2. List the active faults:
      
      faultmgmtsp> fmadm faulty -a
       
   3. If the newly replaced component is still listed as a fault, it can be cleared by using the replaced option on the appropriate slot number:
      
      faultmgmtsp> fmadm faulty replaced DIMM_##
       
      
      NOTE: DIMM slots are 0-7 and 8-15, left to right when viewed from front of MaxRep3 Engine.  Only slots, 0, 2, 8 & 10 are populated.
       
   4. Confirm fault is cleared:
      
      faultmgmtsp> fmadm faulty -a
      No faults found
      faultmgmtsp> exit
      
      
      
6. When finished, re-enable Call-Home.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Confirm that the replacement DIMM was successful - the Warning under Status Summary in the Oracle FS System Manager GUI associated with it and the Open Problem in the ILOM both should be gone.
