TPD_SystemVolume
Associations between
TPD_StorageSystem
and
StorageVolumes
, including physical copies
and snapshots.
TPD_DynamicStoragePool
TPD_DeltaReplicaStoragePool
associated to a CPVV is allocated from
DynamicStoragePool
.
SA/SD Space as StoragePool
A prerequisite for creating snapshots is the allocation of SA and SD spaces to the source volume.
This is done during volume creation time or during modify volume operation.
TPD_DeltaReplicaStoragePool
, sub classed from
CIM_StoragePool
, represents this space.
Snapshot volumes are associated via
TPD_AllocatedFromStoragePool
to the
TPD_DeltaReplicaStoragePool
instead of a concrete
TPD_StoragePool
. There are two
ways to create a
DeltaReplicaStoragePool
:
Goal StorageSetting
If the
SnapVolumeSize
(
-szs
) or
SnapVolumePercentage
(
-pct
) properties are specified
when creating a legacy volume, or if
DSPName

-cpg
) property is specified when creating a
