How to Replace a Host Adapter

Use this procedure to replace a failed host adapter in a running cluster. Node A in this procedure refers to the node with the failed host adapter you are replacing. Node B is a backup node.

1. Determine the resource groups and device groups that are running on Node A and Node B.

   Record this information because you will use it in Step 8 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. Shut down Node A.

   # shutdown -y -g0 -i0

4. Power off Node A.

   For more information, see the documentation that shipped with your server.

5. Replace the failed host adapter.

   Contact your service provider to replace the failed host adapter.

6. Power on Node A.

   For more information, see the documentation that shipped with your server.

7. Boot Node A into cluster mode.

   {0} ok boot

   For more information, see the Sun Cluster 3.0 U1 System Administration Guide.

8. 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
