This read-create RowStatus controls creation and deletion of MGC redundancy group entries, supporting createAndGo and destroy (not createAndWait, notInService, or notReady per the description), with mgcRedundancyGrpNum, mgcNumber, and mgcRedundancyGrpPref listed as mandatory parameters for creation. An admin uses this to provision or remove an entire MGC redundancy group definition in one step, provided the mandatory index and preference values are supplied together. Attempting to create a row without setting those mandatory parameters would fail, since the description states they must be provided as part of row creation.
