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 on Geographic Edition clusters and nodes, see Chapter 5, Administering Cluster Partnerships, in Oracle Solaris Cluster Geographic Edition System Administration Guide .
Instead, perform a cluster shutdown after you complete these steps.
ok> boot -x
Rename one node at a time.
# clnode rename -n newnodename oldnodename
# sync;sync;sync;reboot
# 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.
