Caution

When you add the cluster you’re logged into to an existing supercluster, virtually all of that cluster’s data and configuration are replaced by the shared data and configuration of the supercluster. This includes, among other things, users, groups, conference rooms, site topology, Conference Manager configuration, Call Server configuration, and integrations.

When you create a new supercluster, the data and configuration of the cluster you’re logged into are replaced by the data and configuration of the cluster to which you’re pointing it.

Be sure you create a new supercluster by joining the cluster you’re logged into to the cluster that has the data and configuration you want to preserve. For instance, if one of the clusters is integrated with your Polycom RealPresence Resource Manager or CMA system, join the other cluster to it, not the other way around.

Note

You can’t add a Polycom RealPresence Resource Manager or CMA system to a supercluster or create a supercluster with a Polycom RealPresence Resource Manager or CMA system. But you can integrate a Polycom DMA cluster with a Polycom RealPresence Resource Manager or CMA system in order to get site topology and user-to-device association data from the latter (see “Resource Management System Integration” on page 185). You can do this either before or after creating a Polycom DMA supercluster. The site topology and user-to-device association data is replicated throughout the supercluster.

If a supercluster exists, the Remove from Supercluster command lets you remove the cluster selected in the list from the supercluster, re-initializing it as a new stand-alone cluster. It retains the data and configuration from the supercluster (including site topology), but that data is no longer synchronized to the common data store. If the cluster you’re removing is responsible for any territories (as primary or backup), you must first reassign those territories. The cluster being removed may be either the one you’re logged into or another cluster. The system prompts you to confirm.

The Busy Out command gracefully winds down the use of the selected cluster:

•Existing calls and conferences on the selected cluster continue, but no new conferences are allowed to start. New calls are allowed to start only if they are associated with existing conferences. Registrations are rejected, except for endpoints currently involved in calls. The cluster ceases to manage bandwidth.

•Territories for which the selected cluster has primary responsibility and a different cluster has backup responsibility are transferred to the backup cluster.

•Registrations are seamlessly transferred to the backup cluster (for endpoints that support this). Bandwidth usage data for ongoing calls is seamlessly transferred to the backup cluster.
