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 the following locations:
Any naming services that are used
The local /etc/inet/hosts file on each cluster node, after you install Solaris software
For Solaris 10, the local /etc/inet/iphosts file on each cluster node, after you install Solaris software
For more information about planning IP addresses, see System Administration Guide, Volume 3 (Solaris 8) or System Administration Guide: IP Services (Solaris 9 or Solaris 10).
For more information about test IP addresses to support IP Network Multipathing, see IP Network Multipathing Administration Guide.
