Sun Cluster Software Installation Guide for Solaris OS

IP Addresses

You must set up a number of IP addresses for various Sun Cluster components, depending on your cluster configuration. Each node in the cluster configuration must have at least one public-network connection to the same set of public subnets.

The following table lists the components that need IP addresses assigned. 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 Solaris software.
