Configuring Mediators When Migrating From Solstice HA 1.3 to Sun Cluster 2.2

This section is only relevant to clusters that were originally set up under Solstice HA 1.3 using Solstice DiskSuite mediators (two-string configurations). It describes changes that are automatically made to a mediator configuration when you upgrade from Solstice HA 1.3 to Sun Cluster 2.2. There is no direct user impact, but you should note the changes in any configuration information you keep on the cluster.

The Solstice HA 1.3-to-Sun Cluster 2.2 upgrade procedure documented in the Sun Cluster 2.2 Software Installation Guide changes the Solstice HA 1.3 mediator configuration. The original Solstice HA 1.3 mediator configuration resembles the following:

After running the Sun Cluster 2.2 upgrade procedure, this configuration is converted to one similar to the following:

In Solstice HA 1.3, the hosts referred to the private links by physical names, whereas in Sun Cluster 2.2, the private link IP addresses are used.
