14. DeltaReplicaPoolAccess - Indicates that a specialized pool is required as a container for delta replica elements. In our case, delta replica (virtual copy snapshots) always requires a specialized pool, the TPD_DeltaReplicaStoragePool, which corresponds to the SA/SD space of the base volume. Possible values are: a. Any - specialized pool not required for delta replicas. This is not the case for our snapshots. b. Shared - a single shared pool is required for all delta replicas. This is not the case for our snapshots. c. Exclusive - one specialized, exclusive pool must be created for each source element that has associated delta replicas. This is the only supported value for a virtual copy.
