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.

• For more information about IP addresses, see System Administration Guide, Volume 3 (Solaris 8) or System Administration Guide: IP Services (Solaris 9).

• For more information about test IP addresses to support IP Network Multipathing, see IP Network Multipathing Administration Guide.

Table 1–3 Sun Cluster Components That Use IP Addresses

Component	Number of IP Addresses Needed
Administrative console	1 per subnet
IP Network Multipathing groups	Single-adapter groups – 1 Multiple-adapter groups – 1 primary IP address plus 1 test IP address for each adapter in the group
Cluster nodes	1 per node, per subnet
Domain console network interface (Sun FireTM 15000)	1 per domain
Console-access device	1
Logical addresses	1 per logical host resource, per subnet
