SpaceConsumed
of the TPD_AllocatedFromStoragePool between the concrete pool and
TPD_DeltaReplicaStoragePool equals to the sum of the raw admin and raw snap user
size.
SpaceLimit and SpaceLimitWarningThreshold are both NULL since these
properties apply only to CPVV.
SpaceConsumed by Replica Pool from Concrete Pool = raw SD size + raw SA size
SpaceConsumed of the TPD_AllocatedFromStoragePool between
TPD_DeltaReplicaStoragePool and a snapshot volume equals the space consumed by the
snapshot. This value should be updated via the
UpdateDeltaSnapshotSpace() method to
prevent it from getting too stale.
SpaceConsumed by Snapshot Vol from Replica Pool = space used by a snapshot
5.10.3.3.2 CPVV
When a base volume is created with a StorageSetting in which TSPName is specified, the
resulting
TPD_DeltaReplicaStoragePool is allocated from the DSP. A
TPD_AllocatedFromStoragePool association is created between the
TPD_DeltaReplicaStoragePool and the parent DSP.
TPD_AllocatedFromStoragePool.SpaceLimit and
TPD_AllocatedFromStoragePool.SpaceLimitThresholdWarning of this association
corresponds to the allocation limit (
-al) and allocation warning (-aw) respectively.
SpaceLimit = (Source Volume Size * al)/100
SpaceLimitWarningThreshold = aw
FYI,
SpaceLimit is the consumption limit for the allocated
TPD_DeltaReplicaStoragePool from the associated DSP in bytes.
SpaceLimitThresholdWarning indicates when a warning indication should be generated
based on the total amount of space consumed being greater than or equal to
(
SpaceLimit*SpaceLimitWarningThreshold)/100. A SpaceLimit value of 0 (default)
means that no limit is specified.
SpaceLimitThresholdWarning is meaningless if
SpaceLimit is 0.
SpaceLimit and SpaceLimitThresholdWarning for the
TPD_AllocatedFromStoragePool association between the snapshot volume and the
parent
TPD_DeltaReplicaStoragePool are not used, and hence is not populated, since the
InformOS does not support specification of allocation limit on a per snapshot volume basis.
Calculation for
TotalManagedSpace of the TPD_DeltaReplicaStoragePool of a CPVV is
the similar to that for a non-CPVV, except that the parent pool is now a DSP and not a concrete
