How to Replace an Exadata X7-2 Storage Cell Server M.2 SSD Disk and/or Riser Card.

Solution

DISPATCH INSTRUCTIONS:

WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?:
Exadata X7-2 Training

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: An Exadata X7-2 Storage Cell Server M.2 SSD Disk or Riser 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:

The M.2 SSD disk and riser is hot-pluggable and can be replaced when the power is on. 

The slot location of the failed M.2 SSD disk or riser can be verified with the following command:

These steps are also provided in the documentation:

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

Prepare the Server for Service

M.2 SSD Disks and riser are hot-pluggable and do not require you to power off the server.

1. Locate the cell that has the white LED lit that requires maintenance.
2. Extend the server to the maintenance position
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 Faulty M.2 SSD Disk or Riser

1. Identify and note the location of the faulty M.2 SSD disk by pressing the Fault Remind button on the motherboard, and reviewing the cell alert message details.  The faulty M.2 SSD disk is identified with a corresponding amber LED on the M.2 SSD riser board.

• If the M.2 SSD fault LED is off, then the M.2 SSD is operating properly.
• If the M.2 SSD fault LED is on (amber), then the M.2 SSD is faulty and should be replaced.

2. Remove the M.2 SSD riser board as follows:
   a. Rotate the two M2. SSD riser board socket ejectors outward as far as they will go.

   b. Carefully lift the flash riser board straight up to remove it from the sockets, and place the riser board on an anti-static mat.

3. Using your fingers, push the plastic retainer clip through the riser board to release the M.2 SSD Disk from the M.2 SSD riser board.

4. Remove the plastic retainer clip from the M.2 SSD Disk.  

5. Remove the M.2 SSD Disk from the M.2 SSD riser board as follows:
      a. Lift up on the end of the M.2 SSD Disk approximately one-half inch to one inch (1cm to 2.5cm), in the location where the plastic retainer clip was removed.
      b. Gently slide the M.2 SSD disk rearward and out of the connector to disengage the M.2 SSD disk contacts from the M.2 SSD riser board socket.
      c. Place the M.2 flash SSD on an anti-static mat.

Installing a M.2 SSD Disk into the M.2 SSD Riser

1. Unpack the replacement M.2 SSD Disk or Riser and place it on an anti-static mat.

2. Align and insert the plastic retainer clip into the slot on the M.2 SSD Disk.

3. Hold the M.2 SSD Disk so that the end containing the plastic retainer clip is approximately one-half to one inch (1cm to 2.5cm) above the riser board and the other end is adjacent to the riser SSD socket.

4. Gently slide the M.2 SSD Disk forward and into the connector to engage the contacts in the M.2 SSD riser board socket.    

5. Using your fingers, push down on the end of the card containing the plastic retainer clip until the M.2 SSD Disk snaps into place on the riser board.

You will hear an audible click when the M.2 SSD Disk is secured to the M.2 SSD riser board.

Installing the M.2 SSD Riser

1. Ensure that the ejector tabs in the motherboard connector slot are in the open position.

2. Align the notch in the replacement riser board with the connector key in the connector socket.
   The notch ensures that the riser board is oriented correctly.

3. Push the riser board into the connector socket until the riser board is securely seated in the socket.

4. Rotate the riser board socket ejectors inward until the ejector tabs lock the riser board in place.
   The green power LED on the riser board turns on when you close the socket ejectors.

Return the Server to Operation

1. Install the server top cover. Use a Torx T10 screwdriver to lock the release button latch.
2. Return the server to the normal rack position.

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:

After the M.2 SSD disk is replaced, Exadata Storage Server Software automatically adds the new device to the system partition and starts the rebuilding process.

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 the system disks have active sync status or are being rebuilt:

3. Verify there are no outstanding faults in ILOM:

4. Verify there are no outstanding alerts in the Cell:
