Replacing the SAN Volume Controller 2145-8A4 system board

All the components that were removed when you removed the system board are reused during the installation of the new system board.

1. Align the system board with the chassis, and replace the eight screws that you removed
2. Orient the microprocessor retention module as shown in Figure 1.
   Figure 1. The SAN Volume Controller 2145-8A4 microprocessor bracket frame fully opened
   Attention: In the following step, do not overtighten the screws or touch the system board with the screwdriver. Tighten the screws only until they are snug, and then tighten them an additional quarter turn.
3. Replace the microprocessor retention module. Gently secure it with the four screws that you removed.
4. Replace the microprocessor, heat sink, and air baffle. See Replacing the microprocessor.
5. Replace the memory modules. See Replacing the memory modules (DIMM).
6. Replace the fan connectors. See Replacing the fans.
7. Reconnect the cable to the IDE connector.
8. Reconnect the cables to the front USB and the front panel sockets.
9. Replace power connectors P1 and P6.
10. Replace the riser-card and fibre-channel adapter, and place them on a static-protective surface for reinstallation. See Replacing the fibre-channel adapter assembly.
11. Replace the top cover. See Replacing the top cover.
    
12. You must change a BIOS configuration setting before SAN Volume Controller can operate. Ensure that you read and understand these next steps before you proceed because some panels time out when there is no input for 30 seconds.
    1. Connect a display and keyboard to the node.
    2. Connect a power cable (it does not need to be from the 2145 UPS-1U).
    3. Turn on the node.
       
13. A number of messages are displayed and then message 3001 is displayed:

    ERROR
    3001 SMART Failure Predicted on Hard Drive

    This prediction is not correct. It is displayed because the SAN Volume Controller front panel attaches as a disk drive. After a short pause, the Setup Utility main menu is displayed, but the menu exits if you do not perform an action within 30 seconds.

    Perform the following steps to change the BIOS configuration setting:

    1. Press the down arrow key to move to the Start Options menu and press the Enter key to select it. The current start options settings are displayed.
    2. Press the down arrow to move to the HDD S.M.A.R.T. Capability option and press the right arrow key to change it to Disabled.
    3. Press the Esc key to return to the main menu and then press the down arrow key to move to the Save Settings option.
    4. Press the Enter key to select it and then press the Enter key again to confirm that you want to save the settings.
14. After you have saved the settings, press the power button on the operator-information panel to turn off the node. Remove the power cable, keyboard, and monitor.
15. Place the node in the rack. See Replacing the SAN Volume Controller in a rack.
    
16. Reconnect the fibre-channel and Ethernet cables. Ensure that you replace the fibre-channel and Ethernet cables in the same ports from which they were removed.
    
17. Replace the cable-retention bracket. See Replacing the cable-retention bracket.
    
18. Turn on the node. Wait for the front-panel display to remain stable for at least five minutes before taking any further action.
    • If the repair has been successful and if the node was able to save its state data before shutting down, the node starts and rejoins the cluster. The front panel displays Cluster: and a cluster name if the node has rejoined a cluster.
    • If the repair has been successful but the node was not able to save its state data before shutting down, the node displays node error 578. Follow the procedures in Deleting a node from a cluster using the SAN Volume Controller Console to delete the node from the cluster and then add it back into the cluster. If more than one node has failed, ensure that the node is added back into its original I/O group. See Adding a node to a cluster for more information.
    • If any other message is shown on the front panel, use MAP 5000: Start to resolve the problem.
    Note: It is essential that you perform all the stages of the next step to ensure that the replacement system is set to the serial number of the original machine. Failure to do this might invalidate the customer's warranty or service agreement.
19. After you make sure that the node is operating as part of the cluster, perform the following steps to restore the original machine serial number to the new system board:
    1. Start the command-line interface (CLI). See Accessing the SAN Volume Controller CLI.
       
    2. Write down the 7-character serial number from the serial number label that is on the front of the node. Ignore any hyphens (-) in the serial number.
       
    3. On the front-panel display, press and release the down button until the Node panel is displayed. Write down the node name that is shown on the bottom line.
    4. Issue the following command, substituting the values for nodeserialnumber and nodename that you wrote in the previous steps:

       svctask writesernum -sernum nodeserialnumber nodename

       where nodeserialnumber is the serial number on the front of the node and nodename is the name of the node.

       For example, to write the machine serial number to the system board when the serial number is "13-FEDCB" and the node name is "ZYXW3," you would issue the following command:

       svctask writesernum –sernum 13FEDCB ZYXW3

       Note: The node will restart as soon as the serial number has been written to it.
