3 If this cluster is part of a supercluster and you’re rolling back after rejoining the supercluster, do the
following:
a If integrated with a Polycom RealPresence Resource Manager system, go to Admin >
Integrations > RealPresence Resource Manager and terminate the integration.
b Go to Network > Site Topology > Territories and reassign the cluster’s territory responsibilities.
Wait a few minutes and verify on another cluster that the change has been replicated.

to remove the cluster, click Yes.

servers’ LCDs display DMA Clustered (in a single-server system, the LCD displays DMA Ready),
