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
Component |
Number of IP Addresses Needed |
---|---|
1 IP address per subnet. |
|
1 IP address per node, per subnet. |
|
1 IP address per node, per subnet. |
|
1 IP address per domain. |
|
(Optional) Non-global zones |
1 IP address per subnet. |
1 IP address. |
|
Logical addresses |
1 IP address per logical host resource, per subnet. |
Quorum server |
1 IP address. |
