The private hostname is the name that is used for internode communication over the private-network interface. Private hostnames are automatically created during Sun Cluster configuration of a global cluster or a zone cluster. These private hostnames follow the naming convention clusternodenodeid -priv, where nodeid is the numeral of the internal node ID. During Sun Cluster configuration, the node ID number is automatically assigned to each voting node when the node becomes a cluster member. A voting node of the global cluster and a node of a zone cluster can both have the same private hostname, but each hostname resolves to a different private-network IP address.
After a global cluster is configured, you can rename its private hostnames by using the clsetup(1CL) utility. Currently, you cannot rename the private hostname of a zone-cluster node.
For the Solaris 10 OS, the creation of a private hostname for a non-global zone is optional. There is no required naming convention for the private hostname of a non-global zone.
