HP 3PAR CIM API Programming Reference (OS 3.1.2 MU2) (QL226-97015, June 2013)

Replication Group Key features:
• A group can be the source and/or the target of a copy operation, i.e., volume set
• Elements of a group may be optionally declared copy relations Consistent
• A group may contain zero elements (an empty group)
Volume set is represented by the TPD_ReplicationGroup class, derived from
CIM_ReplicationGroup class. This profile enables management of replication group itself
(create, delete, add member, remove member) as well as copying of the group.
SMI-S also specifies that synchronized groups can maintain replication relationship through the
GroupSynchronized association, as opposed to StorageSynchronized with single volume pair.
InForm OS tracks only the copy relationships between the individual volumes of a vvset, but not
of the vvset itself, hence GroupSynchronized association is not supported for local replication.

ElementName contains the name of the
VV set.

ID contains the system-assigned ID of
the VV set.
vvset IDID
Within the scope of an array, the
InstanceID opaquely and uniquely
identifies an instance of this class

If false, the group, not the elements
associated with the group, may be
TruePersistent
deleted at the completion of a copy
operation. This is always true.
If true and empty groups are allowed,
the group will be deleted when the last
FalseDeleteOnEmptyElement
element is removed from the group. If
empty groups are not allowed, the
group will be deleted automatically
when the group becomes empty.
HP supports empty set and thus this will
always be false.
If true, the group will be deleted when
the group is no longer associated with
FalseDeleteOnUnassociated
another group. This can happen if all
synchronization associations to the
individual elements of the group are
dissolved.
VV set can exist without a
synchronization relationship, thus this
will always be false.
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.
