CIM API Programming Reference
4 SupportedSpecializedElements[] - Enumeration indicating which specialized
storage element types are supported by this instance of StorageReplicationCapabilities.
Example values are “Delta Pool”, “Delta Snapshot”, “Full Snapshots”. This affects the value
of
IntendedUsage property of StorageSetting, e.g., if “Delta Snapshot” is defined
here, then this indicates to a CIM client that a
StorageSetting can be created with
IntendedUsage set to “Delta Snapshot”, which limits the StorageSetting to only
delta snapshot creation. However, for the 3PAR Inform OS,
StorageSetting cannot be
specified for the replica volume during a physical or virtual copy creation, which means
only a value of “Not Specialized” (0) is supported for
StorageSetting. IntendedUsage.
In other words, we cannot specialize a
StorageSetting to only be used as a goal for
creating replica volumes since that is not supported (
StorageSetting can only be used as
a goal in a base volume creation). Thus, we cannot specify “
Full Snapshot” nor “Delta
Snapshot
” here. Value can only contain the following:
a
Delta Pool – StoragePool corresponding to the SA/SD spaces of a volume, valid
only for virtual copy. This indicates to the CIM client that a specialized pool exists from
which to allocate a delta snapshot replica. Since our provider does not support
StoragePool creation, a client cannot set
StorageSetting.IntendedUsage to
“
Delta Pool” either.
5
InitialReplicationState – initial state of the replica after it is first created, supported
values are:
a
Initialized – Resynchronization or copy task is queued but the copy engine has not
started. This is the initial state for a physical copy.
b
Idle - an UnSyncAssoc replica is ready to be managed. This is the initial state for a
virtual copy.
6
SupportedModifyOperations[] - Enumeration indicating which
TPD_StorageConfigurationService.ModifySynchronization() Operation are
supported by this instance of
StorageReplicationCapabilities. Valid values are
outlined in section,
ModifySynchronization().
7
ReplicaHostAccessibility - Indicates host access restrictions for replicas with these
capabilities. Valid values are:
a
Not accessible – this applies to physical copy volumes, which cannot be exported. If
a physical copy is promoted to a base volume, then this restriction is lifted.
b
No restrictions – any host may access; this applies to virtual copy volumes.
