Planning the Sun Cluster Geographic Edition Environment

This section provides guidelines for planning and preparing the following components for Sun Cluster software installation:

• Licensing

• Logical Addresses

Licensing

Ensure that you have available all necessary license certificates before you begin software installation. Sun Cluster Geographic Edition software does not require a license certificate. However, each node that is installed with Sun Cluster Geographic Edition software must be covered under your Sun Cluster Geographic Edition software license agreement.

For licensing requirements for data replication software and application software, see the installation documentation for those products.

Logical Addresses

The Sun Cluster Geographic Edition software uses the logical hostname of a cluster for inter-cluster management communication and heartbeat communication. A logical hostname must be the same as the name of the cluster and be available on the namespace of each cluster.

To find the name of the cluster, run the following command:

# scconf -p | head -2

For more information, see the scconf(1M) man page.
