Sun Cluster Software Installation Guide for Solaris OS

Private Hostnames

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. 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 node when the node becomes a cluster member. After the cluster is configured, you can rename private hostnames by using the clsetup(1CL) utility.

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.
