How to Change Private Hostnames

Perform this task if you do not want to use the default private hostnames (clusternodenodeid-priv) assigned during Sun Cluster software installation.

This procedure should not be performed after applications and data services have been configured and started. Otherwise, an application or data service might continue using the old private hostname after it has been renamed, causing hostname conflicts. If any applications or data services are running, stop them before performing this procedure.

1. Become superuser on a node in the cluster.

2. Start the scsetup(1M) utility.

   # scsetup

3. To work with private hostnames, type 4 (Private hostnames).

4. To change a private hostname, type 1 (Change a private hostname).

   Follow the prompts to change the private hostname. Repeat for each private hostname you want to change.

5. Verify the new private hostnames.

   # scconf -pv | grep 'private hostname' (phys-schost-1) Node private hostname:      phys-schost-1-priv (phys-schost-3) Node private hostname:      phys-schost-3-priv (phys-schost-2) Node private hostname:      phys-schost-2-priv
