15.
If you removed any Fibre Channel or Ethernet cables, use the labels you placed on each cable to
replace all Fibre Channel and Ethernet cables in the same ports from which they were removed.
16.
If you removed the power cords, replace the power cords and the cable-retention brackets, as
described in “Replacing the cable-retention bracket” on page 39.
17.
Lift the locking levers (
1
in Figure 291) on the slide rails and push the server
2
all the way into
the rack until it clicks into place.
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 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.
v
If any other message is shown on the front panel, use MAP 5000 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).
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:
writesernum -sernum
nodeserialnumber nodename
where
nodeserialnumber
is the serial number on the front of the node and
nodename
is the name of
the node.
