FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS: 

PROBLEM OVERVIEW: An Oracle Server X5-2, X6-2 Memory DIMM needs replacement 

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

If the system is still up and functioning, customer should perform an orderly and graceful shutdown of applications and OS.  Then power off the server and remove the AC power cords from the system.

A data backup is not a prerequisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

X6-2 DIMM Population Rules:
http://docs.oracle.com/cd/E62159_01/html/E62171/gntoq.html#scrolltoc

A. Prepare the server for service.

1. Power off the server and disconnect the power cords from the power supplies.
2. Extend the server to the maintenance position in the rack.
3. Attach an anti-static wrist strap.
4. Remove the top cover.

B. Identify and remove the DIMM, confirm population rules (for complete DIMM population rules reference the Service Manual).

1. Do not populate any DIMM sockets next to an empty processor socket. Each processor contains a separate memory controller.

2. The server supports 32-GB quad-rank (QR) Load-Reduced DIMMs (LRDIMMs) and 8-GB single-rank (SR) and 16-GB dual-rank (DR) Registered DIMMs (RDIMMs).

3. Do not mix 32-GB LRDIMMs and 8-GB or 16-GB RDIMMs in the same server. If the server has 32-GB LRDIMMs installed, you cannot install 8-GB or 16-GB RDIMMs and vice versa.

4. Within a memory channel, DIMMs must be populated in the black sockets first, then in the black sockets with white tabs, and then in the white sockets.

   Black Sockets D0/D11/D3/D8

   Black Sockets with white tab : D1/D10/D4/D7

   White Sockets : D2/D9/D5/D6

5. If you are installing a mix of RDIMM sizes (for example, 8-GB and 16-GB), install the larger size RDIMMs first, then the smaller RDIMMs, until all of the RDIMMs are installed.

6. There are no restrictions on the minimum number of DIMM sockets that must be populated. The server will operate properly with one DIMM installed.

7. To confirm and/or identify the location of the failed DIMM press the Fault Remind button on the motherboard. This will light the amber fault LED for the failed DIMM.

8. To remove the DIMM rotate both DIMM socket ejectors outward as far as they will go.

9. Carefully lift the DIMM straight up to remove it from the socket and set it aside on an antistatic mat.

C. Install the replacement DIMM:

1. Unpack the replacement DDR4 DIMM and place it on an antistatic mat.

2. Ensure that the replacement DDR4 DIMM matches the size it is replacing.

3. Ensure that the ejector tabs of the DIMM slot are in the open position.

4. Align the notch in the replacement DIMM with the connector key in the connector socket.  The notch ensures that the DIMM is oriented correctly.

5. Push the DDR4 DIMM into the connector socket until the ejector tabs lock the DIMM in place.

D. Return the Server to operation

1. Replace the top cover

2. Remove any anti-static measures that were used.

3. Return the server to it's normal operating position within the rack.

4. Re-install the AC power cords and any data cables that were removed.

5. Power on server.

E. Check the ILOM to ensure that the fault has been cleared automatically and if not clear it manually.  If the fault has not been cleared automatically, and you have to clear it manually, please make note that you must also reset the server again so the previously mapped out DIMM will be brought online.

1. login to the ILOM CLI and launch a Fault Management Shell session 
   -> start /SP/faultmgmt/shell
   Are you sure you want to start /SP/faultmgmt/shell (y/n)? y
   
   faultmgmtsp>
    
2. use the "fmadm faulty -a" command to list out all active faulty components
   faultmgmtsp> fmadm faulty -a
    
3. If the DIMM that was just replaced is still listed as a fault then indicate that the DIMM has been replaced by using the command "fmadm replaced <fru|cru|uuid>" for example: 
   faultmgmtsp> fmadm replaced /SYS/MB/P0/D2
    
4. confirm that the faults are cleared and then exit out of the fault management shell
   faultmgmtsp> fmadm faulty -a
   No faults found
   faultmgmtsp> exit
   ->

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot up system and verify full functionality
