3.1.2 How to Remove a Cluster Node

The scconf(1M) command enables you to remove nodes by decrementing the number you specified as active nodes when you installed the cluster software with the scinstall(1M) command. For this procedure, you must run the scconf(1M) command on all nodes in the cluster.

1. For an HA configuration, switch over all logical hosts currently mastered by the node to be removed.

   For parallel database configurations, skip this step.

   # haswitch phys-hahost3 hahost1

2. Run the scconf -A command to exclude the node.

   Run the scconf(1M) command on all cluster nodes. See the scconf(1M) man page for details. In this example, the cluster name is sc-cluster and the new total number of active nodes is two.

   # scconf sc-cluster -A 2
