CIM API Programming Reference
2 CopyType – the kind of association between source volume and replica; values are:
a
Sync – create and maintain a synchronous mirror copy of the source, e.g. synchronized
remote copy.
b
Async – create and maintain an async mirror copy of the source e.g., async remote copy.
c
UnSyncAssoc – create and maintain an un-synchronized copy associated to the source,
e.g. virtual copy or physical copy with ‘Save snapshot for later resync’ option turned on.
d
UnSyncUnAssoc – create an un-synchronized clone of the source element and does not
maintain the source association after completing the copy operation, e.g., physical copy
with ‘Save snapshot for later resync’ option turned off.
3
SyncState – state of the association between source volume and replica, e.g.,
ResyncInProgress, RestoreInProgress, Idle, CopyInProgress.
5.10.2.20 TPD_SystemVolume
Associations between TPD_StorageSystem and StorageVolumes, including physical
copies and snapshots.
5.10.2.21 TPD_DynamicStoragePool
TPD_DeltaReplicaStoragePool associated to a CPVV is allocated from
DynamicStoragePool.
5.10.3 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.
5.10.3.1 StoragePool Instantiation
If the SnapVolumeSize (-szs) or DeltaReservationGoal (-pct) or TSPName (-cpg)
option is specified within the input parameter
Goal (a TPD_StorageSetting object) during
a create or modify volume operation, a TPD_DeltaReplicaStoragePool are instantiated
automatically. Creation or modification of this pool via the
CreateOrModifyStoragePool
method are not supported.
