You can change the name of a node that is part of an Oracle Solaris Cluster configuration. You must rename the Oracle Solaris hostname before you can rename the node. Use the clnode rename command to rename the node.
The following instructions apply to any application that is running in a global cluster.
If the cluster where you are performing the rename procedure is primary for the protection group, and you want to have the application in the protection group online, you can switch the protection group to the secondary cluster during the rename procedure.
For more information about administering clusters and nodes in a disaster recovery framework partnership, see Chapter 5, Administering Cluster Partnerships in Administering the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.
Complete the steps in How to Change the Identity of a System in Managing System Information, Processes, and Performance in Oracle Solaris 11.4, except do not perform a reboot at the end of the procedure.
Instead, perform a cluster shutdown after you complete these steps.
ok> boot -x
Rename one node at a time.
# clnode rename -n new-node old-node
# ip-address new-node old-node # clnode rename -n new-node old-node
Once the clnode rename is complete, you can remove the old-node from /etc/host.
# ip-address new-node
# clnode status -v
The configuration information used by the protection groups and your data replication product might specify the node name.
See How to Change the Logical Hostnames Used by Existing Oracle Solaris Cluster Logical Hostname Resources for instructions on this optional step.
