How to Replace a Host-to-Hub Component

Use this procedure to replace the following host-to-hub components.

• Host-to-hub fiber-optic cable

• FC-100/S host adapter GBIC

• FC-100 hub GBIC that connects a Sun StorEdge FC-100 hub to a node

1. On the node that is connected to the host-to-hub connection you are replacing, determine the resource groups and device groups that are running on this node.

   # scstat

2. Move all resource groups and device groups to another node.

   # scswitch -S -h nodename

3. Replace the host-to-hub component.

   For the procedure on replacing a fiber-optic cable, see the Sun StorEdge T3 Configuration Guide. For the procedure on replacing an FC-100 hub GBIC, see the FC-100 Hub Installation and Service Manual. For the procedure on replacing a FC-100/S host adapter GBIC, see your host adapter documentation.

4. Return the resource groups and device groups you identified in Step 1 to the node that is connected to the host-to-hub connection you replaced.

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