HP 3PAR InForm OS 3.1.1 CIM API (QL226-96591, July 2012)

as the SystemElement and those in the asynchronous periodic 3PAR array will be picked as
SyncedElement. The reason for this is that if the primary 3PAR array goes down, by default the
synchronous 3PAR array will assume the primary role.
Under normal operation, this StorageSynchronized will have the following state/status values:
• CopyState – Initialized (2), the link to enable replication is established and source/replica
elements are associated, but the data flow has not started.
• SyncState – Initialized (2), the link to enable replication is established and source/replica
elements are associated, but the Copy engine has not started.
• ProgressStatus – Dormant (3), indicates data flow is inactive.
TPD_ReplicationEntity
Under certain circumstances after the remote replication link goes down, the remote StorageVolume
WWN cannot be calculated. When this happens, the provider will not be able to construct a valid
object path for the remote StorageVolume. Instead, SystemElement or the SyncedElement in question
will contain a reference to a ReplicationEntity, with an InstanceID of 3PAR:<remote volume
name>, and the UndiscoveredElement property will be set to either SystemElement or SyncedElement.
Similiar to remote StorageVolume, this ReplicationEntity cannot be retrieved via
EnumerateInstances/EnumerateInstanceNames.GetInstance.
SyncedElement. Similar to remote StorageVolume, this ReplicationEntity cannot be retrieved via
EnumerateInstances/EnumerateInstanceNames.GetInstance.
ReplicationEntity cannot be discovered via EnumerateInstances, EnumerateInstanceNames nor
GetInstance. It will appear as an instance as a result of an Associators request, and will have the
following value:

DescriptionProperty
3PAR:<remote volume name>InstanceID
StorageVolume (4)Type
Always FALSE, which means that ReplicationEntity will disappear
if link is back up and copy is successful.
Persistent
Remote volume nameEntityID
NULLOtherTypeDescription
Since there is no full-blown support for ReplicationEntity, in the replication service capabilities the
SupportedFeatures property will still include “Requires full discovery of target ComputerSystem“
which indicates that the service does not support undiscovered resources.
TPD_RemoteReplicationGroup
This corresponds to the remote replication group, sub-classed from CIM_ReplicationGroup.
