HP 3PAR InForm OS 3.1.1 CIM API (QL226-96591, July 2012)

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.

TPD_StorageSetting
The provider screens the following properties when a CIM client is creating or modifying a
TPD_StorageSetting object, since only one value is allowed for each. Any other values passed
in by the client results in an Invalid Parameter exception. These properties are initialized with the
allowed value upon creation.
1. PersistentReplica – True indicates the associated replicas persist during power off or
system reset. Only TRUE is accepted since we do not support transient replicas. Applicable
only for those settings that are associated to replica volumes.
2. IntendedUsage – Describes the use of the storage elements associated with this
StorageSetting. This can only be set to “Not Specialized” (0) since we do not support specifying
a StorageSetting as a goal when creating physical or virtual copy.
