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 procedure "How to Upgrade to Sun Cluster 2.2 From HA 1.3" changes the Solstice HA 1.3 mediator configuration. The original Solstice HA 1.3 mediator configuration resembles the following:
Mediator Host(s) Aliases ha-red ha-red-priv1, ha-red-priv2 ha-green ha-green-priv1, ha-green-priv2 |
After running the Sun Cluster 2.2 upgrade procedure, this configuration is converted to one similar to the following:
Mediator Host(s) Aliases ha-red 204.152.65.34 ha-green 204.152.65.33 |
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.
For more information about configuring mediators for Sun Cluster 2.2, see the dual-string mediators chapter in the Sun Cluster 2.2 System Administration Guide.
