If a zone cluster will be configured in an Oracle Solaris Cluster Geographic Edition (Geographic Edition) configuration, the zone cluster must meet the following requirements:
Each zone-cluster node must have a public-network IP address that corresponds to the zone-cluster node's hostname.
The zone-cluster node's public-network IP address must be accessible by all nodes in the Geographic Edition configuration's partner cluster.
Each zone-cluster node must have a failover IP address that maps to the hostname that corresponds to the zone-cluster name.
If you plan to use the Oracle Solaris Cluster Manager GUI to administer Geographic Edition components, all cluster nodes must have the same root password. For more information about Oracle Solaris Cluster Manager, see Chapter 13, Using the Oracle Solaris Cluster GUI, in Oracle Solaris Cluster System Administration Guide .
