HP 3PAR CIM API Programming Reference (OS 3.1.2 MU2) (QL226-97015, June 2013)
non-legacy volume, within the input parameter Goal (a TPD_StorageSetting object) during
create or modify volume operation, a TPD_DeltaReplicaStoragePool will be instantiated
automatically.
CreateOrModifyStoragePool
DeltaReplicaStoragePool can also be created by CreateOrModifyStoragePool method (see Section
(page 31) for the method signature). Following table outlines the parameters for this method:

Note that using this way of creating DeltaReplicaStoragePoolis a two-step process: (1)
create the volume, then (2) create the DeltaReplicaStoragePool.
Associations
TPD_ReplicaPoolForStorage
The TPD_DeltaReplicaStoragePool is associated to the source StorageVolume via
TPD_ReplicaPoolForStorage.
TPD_AllocatedFromStoragePool
New instances of TPD_AllocatedFromStoragePool are created that associate the
TPD_DeltaReplicaStoragePool to:
• the parent StoragePool. For non-CPVV, the parent pool is a concrete pool, and whether
this is all-FC, all-NL, or all-SSD depends on the device type of the source volume. For CPVV,
the parent pool is a DSP.SpaceConsumed property in either case is the sum of raw snap
volume size and raw admin size. SpaceLimit and SpaceLimitThresholdWarning are
valid only for CPVV.
• all virtual copy snapshot volumes that are created from the source volume. SpaceConsumed
property for each association in this case is the space consumed by the snapshot.
