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 Sun 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.

1. Become superuser on a node in the cluster.

2. Start the scsetup(1M) utility.

   # scsetup

3. From the Main Menu, choose Private hostnames.

4. From the Private Hostname Menu, choose Change a private hostname.

5. Follow the prompts to change the private hostname.

   Repeat for each private hostname to change.

6. 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

7. Did you install your own /etc/inet/ntp.conf file before you installed Sun Cluster software?

   • If no, go to How to Configure Network Time Protocol (NTP) to install or create the NTP configuration file.

   • If yes, proceed to Step 8.

8. Are you using Sun Cluster on a SPARC based system and you intend to use Sun Management Center to monitor the cluster?

   • If yes, go to SPARC: Installing the Sun Cluster Module for Sun Management Center.

   • If no, install third-party applications, register resource types, set up resource groups, and configure data services. See the documentation that is supplied with the application software and the Sun Cluster Data Service Planning and Administration Guide for Solaris OS.
