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 4-7 section.
• A server with Secondary status can be manually changed to Deactivated status. See the Manually
Activating a Server with Deactivated Status, page 4-8 section.
• 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 4-8 section.
