Copy group function
Defining a copy group by specifying two device groups: one device group
from primary side and one device group from secondary side, whether they
are inside or outside the storage system. A copy group cannot be defined by
specifying more than one device group from just one side of primary or
secondary.
When a copy group is created, which device group is primary and which is
secondary cannot be specified. Therefore, it is specified at the time of actual
CCI functions
