How to Replace a Host Adapter

Use this procedure to replace a failed host adapter in a running cluster. The node in this procedure refers to the node with the failed host adapter you want to replace.

1. Move the node's services to the other node within the cluster, stop Sun Cluster software from running, and then shut down the node.

   # haswitch nodename logicalhost # scadmin stopnode # shutdown -y -g 0

   For the procedure on shutting down a node, see the Sun Cluster 2.2 System Administration Guide.

2. Power off the node.

3. Replace the failed host adapter.

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

4. Power on the node.

5. Boot the node to prepare it for cluster mode.

   {0} ok boot

6. Log on and bring the node into cluster mode.

   If this is the first node in the cluster:

   # scadmin startcluster hostname clustername

   If this is not the first node in the cluster:

   # scadmin startnode
