TPD_RemoteReplicationGroup, Replication Group Key features

Page 104 highlights

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. Table 91 Relevant Properties of ReplicationGroup Class Properties ElementName ID InstanceID Persistent DeleteOnEmptyElement Value vvset name vvset ID HP_3PAR: True False Description ElementName contains the name of the VV set. ID contains the system-assigned ID of the VV set. 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 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 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. DeleteOnUnassociated False If true, the group will be deleted when the group is no longer associated with 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. 104 CIM API SMI-S Support

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.

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.
