PROBLEM OVERVIEW: An Oracle Server X7-2 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.

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.
3. Attach an antistatic wrist strap to your wrist and then to a metal area on the chassis.
4. Remove the server top cover.

           a. If the release button latch is in the locked position, use a Torx T10 screwdriver to turn the release button latch clockwise to the unlocked position.
           b. Lift up on the release button on top of the server cover. Lifting the release button causes the server cover to slide toward the rear of the chassis for easy removal.
           c. Lift up and remove the top cover

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

1.      The population rules for adding DIMMs to the server are as follows:

• • The server supports 64-GB quad-rank (QR) Load-Reduced DIMMs (LRDIMMs) and 32-GB dual-rank (DR) and 16-GB DR Registered DIMMs (RDIMMs).
  • Do not mix 64-GB LRDIMMs and 16-GB or 32-GB RDIMMs in the same server. If the server has 64-GB LRDIMMs installed, you cannot install 16-GB or 32-GB RDIMMs and vice versa.
  • Within a memory channel, DIMMs must be populated in the black sockets first, and then in the white sockets.
  • If you are installing a mix of RDIMM sizes (for example, 16-GB and 32-GB), install the larger size RDIMMs first, then the smaller RDIMMs, until all of the RDIMMs are installed.
  • The server operates properly with a minimum of one DIMM installed per processor.
  • In single-processor systems, install DIMMs only into DIMM sockets associated with processor 0 (P0). Starting with socket P0 D7, first fill the black sockets, and then fill the white sockets

      2.   Identify and note the location of the failed DDR4 DIMM by pressing the Fault Remind button on the motherboard

      3.   To remove the failed DIMM do the following:

                a. Rotate both DIMM socket ejectors outward as far as they will go. The DIMM is partially ejected from the socket.
                b. Carefully lift the DIMM straight up to remove it from the socket.

 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 of the DIMM it is replacing.
3. Ensure that the ejector tabs are in the open position.
4. Align the notch in the replacement DIMM with the connector key in the connector socket.
5. Push the DDR4 DIMM into the connector socket until the ejector tabs lock the DIMM in place.
6. Repeat Step 5 until all replacement DDR4 DIMMs are installed.

 D. Return the Server to operation

1. Install the server top cover.
2. Return the server to the normal rack position.
3. Reconnect the power cords to the server power supplies and reconnect the data cables.
4. Wait for ILOM to boot up, and check Oracle ILOM to clear server DDR4 DIMM faults.

                1. login to the ILOM CLI and launch a Fault Management Shell session               

               2. use the "fmadm faulty -a" command to list out all active faulty components

               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:

               4. confirm that the faults are cleared and then exit out of the fault management shell

      5. Power on the server.

E. Check and ensure no faults reported in ILOM and Host OS reported memory capacity correctly.
