HP 3PAR CIM API Programming Reference

4. Locality - specifies the relationship between the source and target element. There are two
defined localities:
a. Local - indicates the source and target elements are contained in a single managed system.
b. Remote - indicates the source and target elements are contained in separate managed
systems. In this case, the service must rely on a networking protocol for the copy
operations. HP 3PAR SMI-S supports read-only implementation of remote replication.
SMI-S terminologies can be mapped to HP terminologies.

TPD_RemoteReplicationGroup
TPD_RemoteReplicationGroup is a copy group that is used for remote copy (remote mirrors),
sub-classed from CIM_ReplicationGroup. Please note that creation, modification and deletion of
RemoteReplicationGroup is not supported.

A remote copy group can be empty.FalseDeleteOnEmptyElement
Remote copy group can exist without
synchronization.
FalseDeleteOnUnassociated
If true, the point-in-time was created at
an exact time with no I/O activities in
TrueConsistentPointInTime
such a way the data is consistent
among all the elements of the group.
