On the Solaris 10 OS, use the naming convention nodename:zonename to specify a non-global zone to a Sun Cluster command.
The nodename is the name of the cluster node.
The zonename is the name that you assign to the non-global zone when you create the zone on the node. The zone name must be unique on the node. However, you can use the same zone name on different nodes, because the different node name in nodename:zonename makes the complete non-global zone name unique in the cluster.
To specify the global zone, you only need to specify the node name.
