You must set up a number of IP addresses for various Geographic Edition components, depending on your cluster configuration. Observe the following guidelines:
You must have an IP address for the cluster name and for each cluster node.
See Public-Network IP Addresses in Oracle Solaris Cluster Software Installation Guide for a list of components that require IP addresses. Add these IP addresses to any naming services that are used. Also add these IP addresses to the local /etc/inet/hosts file on each cluster node after you install Oracle Solaris software.
You might also need additional IP addresses for data replication products. For more information about requirements for configuring data replication, see the Geographic Edition manual for your data replication product.
