Changing Server Status in a Cluster and its Effects

The Unity Connection cluster status can be changed either automatically or manually.

You can manually change the status of servers in a cluster in the following ways:

•A server with Secondary status can be manually changed to Primary status. See the Manually Changing the Server Status from Secondary to Primary, page 4-7section.

•A server with Secondary status can be manually changed to Deactivated status. See the Manually Activating a Server with Deactivated Status, page 4-8section.

•A server with Deactivated status can be manually activated so that its status changes to Primary or Secondary, depending on the status of the other server. See the Manually Activating a Server with Deactivated Status, page 4-8section.
