Removing the SAN Volume Controller 2145-4F2 service controller

Attention: If you are replacing the service controller and the disk drive as part of the same repair operation, see Replacing a disk drive and a service controller on the SAN Volume Controller.

To remove the service controller, perform the following steps:

Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering off a SAN Volume Controller node for more information..
Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
Remove the top cover. See Removing the top cover.
Remove the front panel of the node.
Pull the two handles ( in Figure 1) to release the latches.

Carefully pull the service controller out of the node to avoid damaging the attached cables.
Note: When you replace a service controller, it is normal to change the worldwide node name (WWNN) of the new service controller to match the one that is being replaced. In this case, you will have two service controllers with the same WWNN. Clearly label the service controller that you are removing and indicate that its WWNN is now a duplicate and that it must not be connected to a SAN before its WWNN is reset.
