How to Replace a Node's Host Adapter in a Running Cluster

Use this procedure to replace a failed host adapter in a running cluster. As defined in this procedure, "Node A" is the node with the failed host adapter you are replacing and "Node B" is the other node.

1. Determine the resource groups and device groups running on all nodes.

   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 nodename

3. Shut down Node A.

   # shutdown -y -g0 -i0

4. Power off Node A.

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

5. Replace the failed host adapter.

   For the procedure on removing and adding host adapters, see the documentation that shipped with your nodes.

6. Power on Node A.

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

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 all nodes.

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