How to Replace the Disk Drive Backplane in an Oracle Exalytics X2-4 or X3-4 system

Solution

CAP PROBLEM OVERVIEW:Disk Drive Backplane replacement

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Oracle Exalytics Server Training.

TIME ESTIMATE: 45 minutes

TASK COMPLEXITY: 2-FRU

FIELD ENGINEER INSTRUCTIONS

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

If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS.

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

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. 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.

2. Remove all disk drives

1. For each disk push the disk drive release button to open the latch.
2. Grasp the latch and pull the drive out of the drive slot. The latch is not an ejector. Do not bend it too far to the right. Doing so can damage the latch.
3. Make a note of the slot where each drive is installed so that they can be re-installed in the same locations.
4. Place each disk aside on an antistatic mat.

3. Remove the Disk Drive Backplane

1. Remove the power cable, ribbon data cable, and any SAS/SATA cables from the disk drive backplane.
2. Push up on the wire tab in the upper corner and pull the disk drive backplane up and out of the chassis.
3. set aside on an antistatic mat.

4. Install the replacement Disk Drive Backplane

1. Unpack the replacement disk drive backplane and place it on an antistatic mat.
2. Insert the disk drive backplane into the chassis. Verify that the disk drive backplane is seated properly at the bottom.
3. Lift up the metal hook and press the disk drive backplane to the front until it snaps into place.
4. Replace the power cable, ribbon data cable, and any SAS/SATA cables.
5. The mini-SAS plug that terminates the short SAS/SATA cable must be inserted into the upper mini-SAS connector on the disk backplane. The longer SAS/SATA cable connects drive bays 4 and 5 to a storage device in the rear of the system. The lower mini-SAS connector on the disk backplane requires the standard, four-channel mini-SAS cable for drive bays 0 to 3.

5. Re-install all disk drives

1. Install each disk back into it's slot making sure to replace the drives back into their original position.
2. For each drive verify that the release lever on the disk drive is fully opened.
3. Slide the drive into the drive slot until it is fully seated.
4. Close the latch to lock the drive in place.

6. 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. Verify that the Power/OK indicator led lights steady on.

7. Check the system serial number information (psnc data)

1. login to the ILOM as root and then enter the restricted shell to check the psnc values. Follow the example below to enter restricted shell and use the showpsnc command-  

   -> set SESSION mode=restricted

   [(restricted_shell) exalytics0-sp:~]$showpsnc

   Backup 1: fruid:///SYS/DBP
   Backup 2: fruid:///SYS/MB

2. With a Disk Backplane replacement the system should be able to automatically copy the psnc values from the primary and backup2 containers as long as they match. (if more than one part was replaced at the same time this may not happen)
3. As long as all of the psnc values match and are correct as in the above example this step is done. However if there was an issue during the replacement which caused the psnc values not to propagate automatically then this will need to be fixed manually by using the copypsnc command from service or escalation mode. If you are unfamiliar with this process and require assistance please reference the steps for using copypsnc to fix the serial number detailed in the "How to Replace the Fan Board in an Oracle Exalytics X2-4 or X3-4 system (Doc ID 1598232.1)" and contact the TSC if needed.

8. Allow the system to power up and confirm it functions properly.

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
