Replicated mirror groups are a feature of PowerHA® SystemMirror Enterprise Edition. Replicated mirror groups extend the base capability of PowerHA SystemMirror by providing automated fallover and fallback support. Replicated mirror groups also provide data replication for applications across geographically dispersed systems, which are called sites.
Mirror disk pairs represent the replication
relationship between two disks or two volumes. This relationship must
already be established at the storage level. One of the disks or volumes
in the pair is on the primary site and the other disk or volume is
on the secondary site.

for PowerHA SystemMirror Enterprise Edition topic in the AIX® Information Center.
