FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS

PROBLEM OVERVIEW: An Exadata X7-2 Compute Node Server Memory DIMM needs replacement

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

IMPORTANT NOTE TO TSC ENGINEER: CUT & PASTE the “CUSTOMER ACTIVITY” sections of the Pre-Replacement and Post-Replacement steps into a SR Note and ensure the customer is aware to do these steps prior to the scheduled field engineer activity, and during and after the replacement activity.

CUSTOMER ACTIVITY:

Shutdown of the database node is required prior to the part replacement:

If running Linux or Solaris native - follow Steps 1 to 9 of MOS Note:
How to shutdown the Exadata database nodes and storage cells in a rolling fashion so certain hardware tasks can be performed. (Doc ID 1539451.1)

If running OVM then follow MOS Note:
How to Shutdown and Startup Exadata database nodes running OVM (Doc ID 2367609.1)

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

Prepare the Server for Service

The customer should have already prepared the server and powered it off. If not, provide them the instructions in the previous section.

1. Extend the server to the maintenance position
2. Disconnect the power cords from the power supplies
3. Attach an anti-static wrist strap to your wrist and to a metal area on the chassis or the rack.
4. Remove the server top cover. Use a Torx T10 screwdriver to unlock the release button latch.

Identifying and Removing a Memory DIMM

1. Identify and note the location of the failed DDR4 DIMM by pressing the Fault Remind button on the motherboard.
    Faulty DIMMs are identified with a corresponding amber LED on the motherboard.

• If the DIMM Fault LED is off, then the DIMM is operating properly.
• If the DIMM Fault LED is on (amber), then the DIMM is faulty and should be replaced.

2. 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.

3. Replace each faulty DIMM with another DIMM of the same size.

Installing a Memory DIMM

1. Unpack the replacement DDR4 DIMM and place it on an anti-static mat.

2. Ensure that the replacement DDR4 DIMM matches the size and rank of the DIMM it is replacing.
    You must not replace a dual-rank 32GB DIMM with a quad-rank 64GB DIMM and vice versa. If you violate this rule, the performance of the server might be adversely affected.

3. Install the replacement DDR4 DIMM.

       a. Ensure that the ejector tabs are in the open position.
       b. Align the notch in the replacement DIMM with the connector key in the connector socket.
           The notch ensures that the DIMM is oriented correctly.
       c. Push the DDR4 DIMM into the connector socket until the ejector tabs lock the DIMM in place.
           If the DIMM does not easily seat into the connector socket, verify that the notch in the DIMM is aligned with the connector key in the connector socket. If the notch is not aligned, damage to the DIMM might occur.

Return the Server to Operation

1. Install the server top cover. Use a Torx T10 screwdriver to lock the release button latch.
2. Reconnect the power cords to the server power supply and connect any other cables to their original locations.
3. Return the server to the normal rack position.
4. Once the power cords have been re-attached and the ILOM has booted you will see a slow blink on the green LED for the server. Power on the server by pressing the power button on the front of the unit.
5. Connect to the server console via the ILOM and monitor the boot.
    By default the ILOM serial console displays the primary console output.
    In the event of unexpected boot behavior, it is advisable to connect to both ILOM serial and ILOM graphics consoles at the same time and monitor.

OBTAIN CUSTOMER ACCEPTANCE

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

FIELD SERVICE ENGINEER and CUSTOMER ACTIVITY:

1. Verify all expected hardware is visible to the server and the fault is cleared. Assistance from the customer for server login access will be required.

2. Verify there are no outstanding faults in ILOM:

3. Verify there are no outstanding alerts in the Database Node:

4. Re-enable and restart the Database services:

If running Linux or Solaris native - follow Steps 11 to 14 of MOS Note:
How to shutdown the Exadata database nodes and storage cells in a rolling fashion so certain hardware tasks can be performed. (Doc ID 1539451.1)

If running OVM then follow MOS Note:
How to Shutdown and Startup Exadata compute nodes running OVM (Doc ID 2367609.1)

PARTS NOTE:

7330698 [F] 32GB DDR4-2666 Registered DIMM
7330699 [F] 64GB DDR4-2666 Load Reduced DIMM
