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: Table 43 Creating StoragePool using CreateOrModifyStoragePool Type of Pool CreateOrModifyStoragePool Parameters Goal.

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. 58 CIM API SMI-S Support
