How to Replace a Host-to-Hub/Switch Component

Use this procedure to replace the following host-to-hub/switch components. (StorEdge T3/T3+ arrays in single-controller configuration can be used with Sun StorEdge Network FC Switch-8 or Switch-16 switches when creating a SAN.)

• Host-to-hub/switch fiber-optic cable

• FC-100/S host adapter GBIC

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

1. On the node that is connected to the host-to-hub/switch 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/switch component.

   • For the procedure on replacing a fiber-optic cable, see the Sun StorEdge T3 and T3+ Array 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/switch connection you replaced.

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