Sun Cluster Software Installation Guide for Solaris OS

Public Network IP Addresses

For information about the use of public networks by the cluster, see Public Network Adapters and Internet Protocol (IP) Network Multipathing in Sun Cluster Concepts Guide for Solaris OS.

You must set up a number of public network 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 public network IP addresses assigned. Add these IP addresses to the following locations:
