PROBLEM OVERVIEW: An Oracle Server X5-4 Disk Backplane 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.

Animation videos are available to demonstrate the disk back plane replacement process for these servers. please refer to the following links:

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service. 

a. Power off the server and disconnect the power cords from the power supplies.
b. Extend the server to the maintenance position in the rack.
c. Attach an anti-static wrist strap.

2. Remove all of the disks and Remove the DVD drive. See Remove the DVD Drive.

1.  On each drive, push the latch release button to open the latch.
2.  Grasp the latch and pull the drive out of the drive slot.
3.  Place the drives on an antistatic mat making sure to note the slot locations that the drives were removed from so that they can be re-installed in their proper slots.
4.  Remove the DVD Drive.
5.  Or you may want to disengage the drives and DVD leaving them in their slots removed only an inch or two to ensure drive placement is accurate.
6.  Remove the Memory Riser MR0 so you have room to access the air divider.
7.  Disconnect the SAS cables, NVME Cables, and ESM cable or module in preparation for removing the air divider.
8.  You do not need to remove the cables from the HBA board or the NVME Switch card.

3. To move the air divider:

1.  Move the air divider, so that you can access  the disk drive back plane board. The divider is mounted to the power supply side wall using two tabs, which are inserted into slots in the side wall.
2.  Lift the air divider so the tabs clear the slots in the power supply housing side wall.
3.  Move the air divider away from the side wall, lift it up, and bend the cables, so you can rotate the divider away from the back-plane and set it in the PCIe slot area.
4.  Remove the power cable and data ribbon cable from the disk backplane.
5.  The disk drive back plane sets on metal flanges and is secured by a spring-loaded lever.
6.  To release the disk backplane, lift the spring-loaded lever upward.
7.  To remove the disk drive back plane, lift it, so it clears the support flanges, and remove it from the server.
8.  You might need to tilt the board slightly while removing it to slide the DVD connector out from under the disk drive mounting cage.

4. Install the new storage drive back plane and connect the cables.  

a. Orient the replacement disk drive back plane board in the chassis.
b. Tilt the back plane board and insert its bottom edge in the plastic slot at the bottom of the server.
c. Lift the spring-loaded metal hook and tilt the back plane board to its upright position.
d. Set the board on its support flanges.
e. To secure the board, release the metal hook.
f. Connect the ribbon cable and power cable to the bottom of the board.  

5. To install the air divider:

1. Ensure the SAS/NVME cables are routed through the slot in air divider properly.
2. The back side of the divider has enough room to house the cables if they are flat and side-by-side. Do not allow the cables to interfere with the Fault Remind button mechanism.
3. Align the two tabs on the divider with the three slots in the power supply side wall.
4. Push the tabs into the slots and push the divider downward to secure it against the wall.
5. To ensure proper alignment of the Fault Remind switch, both tabs must be engaged with their slots.

6. Connect the ESM cable or replace ESM with cable to side panel and any SAS/NVME cables.

1.  Install all disk drives and filler panels.
2.  Making sure to install the drives back into the same slots from which they were removed align the drive to the drive slot.
3.  Slide the drive into the bay until the drive is fully seated.
4.  Close the drive latch to lock the drive in place.
5.  Install the DVD drive. See Install the DVD Drive.

7. Return the Server to operation 

a. Remove any anti-static measures that were used.
b. Return the server to it's normal operating position within the rack.
c. Re-install the AC power cords and any data cables that were removed.
d. Power on server. Verify that the Power/OK indicator led lights steady on.

8. Set the system serial number/fruid data if needed.

a. 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-

b. 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.

c. 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 the system may need to be prompted to copy the data by either resetting the ILOM or scheduling a power cycle of the system by shutting down and removing the AC. If the SP reset or power cycle of the system does not synchronize the TLI data this will need to be fixed manually from service or escalation mode. These ILOM modes require a dynamic password and an Oracle Engineer for access. If Service mode is needed please contact the TSC and request assistance.

d.For Field Engineers: 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 update product serial number on systems which implement Top Level Identifier functionality (Doc ID 1280913.1)" and contact the TSC if needed.[This section is not visible to customers.]

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
