How to Change Private Hostnames
Perform this task if you do not want to use the default private hostnames,
clusternodenodeID-priv, that are
assigned during Oracle Solaris Cluster software installation.
Do not perform this procedure after applications and data services have
been configured and have been started. Otherwise, an application or data service might continue to
use the old private hostname after the hostname is renamed, which would cause hostname conflicts. If
any applications or data services are running, stop them before you perform this procedure.
Perform this procedure on one active node of the cluster.
Assume the root role on a global-cluster node.
Start the clsetup utility.
The clsetup Main Menu is displayed.
Type the option number for Private Hostnames and press the Return key.
The Private Hostname Menu is displayed.
Type the option number for Change a Node Private Hostname and press the Return key.
Follow the prompts to change the private hostname.
Repeat for each private hostname to change.
Verify the new private hostnames.
phys-schost# cluster show -t node | grep privatehostname
Update the NTP configuration with the changed private hostnames. Go to How to Update NTP After Changing a Private Hostname.
