The logical hostname is a special high-availability (HA) resource. The geoadm start command configures the logical hostname that corresponds to the cluster name. The IP address and host maps for the logical hostname must be set up before you run this command. Before assigning hostnames, familiarize yourself with the legal names and values that are described in Appendix B, Legal Names and Values of Sun Cluster Geographic Edition Entities.
For more information about using the geoadm start command , see Enabling the Sun Cluster Geographic Edition Software.
If you are using Sun StorageTek Availability Suite for data replication, a logical hostname is created for each device group to be replicated. For more information, see Chapter 1, Replicating Data With Sun StorageTek Availability Suite Software, in Sun Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite.
The following table lists the Sun Cluster and Sun Cluster Geographic Edition components that require IP addresses. Add these IP addresses to the following locations:
All naming services that are being used
The local /etc/inet/ipnodes file on each cluster node, after you install the Solaris OS software
For more information about configuring the IP address and host maps during the installation of Sun Cluster software, refer to Chapter 2, Installing Software on the Cluster, in Sun Cluster Software Installation Guide for Solaris OS.
