Configuring Mediators When Migrating From Solstice HA 1.3 to Sun Cluster 2.2 7/00 Release

This section is relevant only for 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.
