If a protection group contains only one EMC Symmetrix Remote Data Facility device group, then the aggregate device group state is the same as the individual device group state.
When a protection group contains multiple EMC Symmetrix Remote Data Facility device groups, the aggregate device group state is obtained as described in the following table.
