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:
a. 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.
b. 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.
c. Press the Esc key to return to the main menu and then press the down arrow key to move to the
Save Settings option.
d. 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" on page 48.
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" on page 34.
18. Turn on the node. Wait for the front-panel display to remain stable for at least five minutes before
taking any further action.
v 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.
v 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"
in the IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide 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" in the IBM
System Storage SAN Volume Controller 2145 Troubleshooting Guide for more information.
v If any other message is shown on the front panel, use MAP 5000 in the IBM System Storage SAN
Volume Controller 2145 Troubleshooting Guide 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:
a. Start the command-line interface (CLI). See "Accessing the SAN Volume Controller CLI" in the
IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide.
b. 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.
c. 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.
d. 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
