How to Replace a Host-to-Array Fiber-Optic Cable

Use this procedure to replace the host-to-array fiber-optic cables. Node A in this procedure refers to the node with the failed fiber-optic cable that you are replacing.

1. On Node A, determine the resource groups and device groups that are running on this node.

   Record this information because you will use it in Step 4 of this procedure to return resource groups and device groups to these nodes.

   # scstat

2. Move all resource groups and device groups off Node A.

   # scswitch -S -h from-node

3. Replace the host-to-array fiber-optic cable.

4. Return the resource groups and device groups you identified in Step 1 to Node A.

   # scswitch -z -g resource-group -h nodename # scswitch -z -D device-group-name -h nodename
