Public-Network IP Addresses

For information about the use of public networks by the cluster, see Public Network Adapters and 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 Solaris host 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:

• Any naming services that are used

• The local /etc/inet/hosts file on each global-cluster node, after you install Solaris software

• For IPv6 IP addresses on the Solaris 9 OS, the local /etc/inet/ipnodes file on each global-cluster node, after you install Solaris software

• The local /etc/inet/hosts file on any exclusive-IP non-global zone

Table 1–3 Sun Cluster Components That Use Public-Network IP Addresses

Component	Number of IP Addresses Needed
Administrative console	1 IP address per subnet.
Global-cluster nodes	1 IP address per node, per subnet.
Zone-cluster nodes	1 IP address per node, per subnet.
Domain console network interface (Sun FireTM 15000)	1 IP address per domain.
(Optional) Non-global zones	1 IP address per subnet.
Console-access device	1 IP address.
Logical addresses	1 IP address per logical host resource, per subnet.

For more information about planning IP addresses, see Chapter 3, Planning Your TCP/IP Network (Task), in System Administration Guide: IP Services (Solaris 9) or Chapter 2, Planning Your TCP/IP Network (Tasks), in System Administration Guide: IP Services (Solaris 10).
