For information about the use of public networks by the cluster, see Public Network Adapters and IP Network Multipathing in Oracle Solaris Cluster Concepts Guide .
You must set up a number of public-network IP addresses for various Oracle Solaris Cluster components. The number of addresses that you need depends on which components you include in your cluster configuration. Each Oracle Solaris host in the cluster configuration must have at least one public-network connection to the same set of public subnets.
Any naming services that are used
The local /etc/inet/hosts file on each global-cluster node, after you install Oracle Solaris software
The local /etc/inet/hosts file on any exclusive-IP non-global zone
