Changing the Name of a Cluster Node

The names of the cluster nodes can be changed using the scconf(1M) command. Refer to the scconf(1M) man page for additional information.

How to Change the Name of a Cluster Node

1. Find the names of the current cluster nodes.

   You can run the scconf -p command on any node that is an active cluster member.

   # scconf clustername -p Current Configuration for Cluster clustername: Hosts in cluster: phys-hahost1 phys_hahost2 phys-hahost3 Private Network Interfaces for phys-hahost1: be0 be1 phys-hahost2: be0 be1 phys-hahost3: hme0 hme1

2. Run the scconf -h command on all nodes in the cluster.

   Run the scconf(1M) command on all nodes. See the scconf(1M) man page for details.

   # scconf -h clustername hostname0 [...hostname3]

   The new node names should be specified in the order shown by the scconf -p command. For example, to change the name of phys-hahost3 to phys-opshost1, you would run the following command on all cluster nodes.

   # scconf -h sccluster phys-hahost1 phys-hahost2 phys-opshost1
