Solution

DISPATCH INSTRUCTIONS
   WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED: Familiar with oakcli commands on an ODA
   TIME ESTIMATE: 240 Mins
   TASK COMPLEXITY: 4

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
   PROBLEM OVERVIEW: Disk backplane needs to be replaced due to a fault on the backplane
   WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?: Both nodes need to be shutdown, and powered off, power cords unplugged.
   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE: Customer will need to shutdown the OS on both nodes.

1. Prepare the system for service.

    a. Power off the system.
    b. Disconnect the power cords from the system.
    c. If the system is installed in a rack, remove it.
    d. Remove both power supplies from the system.
    e. Attach an antistatic wrist strap.

2. Remove all of the front storage drives.
3. Remove both server nodes from the system.
4. Remove the middle section of the system top cover.
5. Loosen the two captive Phillips screws that secure the side-wall cover to the chassis and remove the cover.
    The side-wall cover is positioned under the middle section of the system top cover. Before you can remove the side-wall cover, you must remove the middle section of the system top cover.
6. Remove the power distribution board.
7. Remove the disk midplane module.

    a. Before disconnecting the two front indicator module (FIM) cable connectors from the disk midplane module, label them.
        The lower connector on the disk midplane is for SN0 and the upper connector is for SN1.
    b. Disconnect the two FIM cable connectors from the disk midplane module.
    c. Remove the Phillips screw that secures the disk midplane module to the disk drive cage.
    d. To remove the disk midplane module from the system chassis, lift the board up about 0.25 inches (6.35 mm) to clear the standoffs that hold it in place.
        To remove the board, it might be necessary to move the bottom of the board away from the disk drive cage to disengage the standoff located at the top, left corner of the board before you can lift the board up and out of the system.
        There are four columns of standoffs, four in the left-most column and three in each of the remaining columns.
    e. Lift the disk midplane module up and out of the system.
    f. Place the board on an antistatic mat.

8. Install the disk midplane module.

    a. Move the front indicator module (FIM) cable connectors toward the rear of the system so that the disk midplane module is not installed over them.
    b. Lower the disk midplane module in the system chassis.
    c. Position the disk midplane module against the disk drive cage, tilting the top slightly forward so that it fits over the top-most standoff on the left side and then position board so that it fits over the remaining 12 standoffs, then push     downward on the board to engage the standoffs.
    d. To secure the disk midplane module to the disk drive cage, install the Phillips screw.
    e. Reconnect the two FIM cable connectors to the receptacles on the disk midplane module.
        Ensure that the FIM connectors are properly connected. The lower connector on the disk midplane is for SN0 and the upper connector is for SN1.

9. Install the power distribution board into the system.

10. Position the side-wall cover into the chassis and tighten the two captive Phillips screws to secure the side-wall cover to the chassis.
11. Install the middle section of the system's top cover.
12. Reinstall all of the front storage drives.
13. Reinstall both server nodes into the system.
14. Return the system to operation.
15. Install both power supplies into the system.
16. If the system was installed in a rack, reinstall it into the rack.
17. Reconnect the power cords to the system and power on the system.

Since the disk backplane has a backup copy of the fruid, the fruid may need to be copied over, if it does not automatically sync to the primary (power dist. board) or backup1 (motherboard).

Login into ILOM of new one of the nodes and confirm serial# is correct. "show /SYS" should show the same serial number of the other node.

If not, use procedure to enter service mode to copy the fruid information from one of the other copies. For example:

# copypsnc primary backup2

Refer to Doc ID 1280913.1 - How to update product serial number on systems which implement Top Level Identifier functionality
