You can remove a node from a cluster by using the cluster unjoin command. Before a node can be successfully removed from a cluster, all of its shared resources, such as virtual interfaces to clients, must be shut down. The command fails if any shared resources are still active.
The command prompts you for confirmation before running.
The following example removes node node0b from cluster Clus1:
node::>cluster unjoin -node node0b -clustername Clus1
