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 pair creation. As configuration information,
a copy group name, a device group name (primary and secondary), and an MU# are maintained
in the storage system.
The notes when operating copy groups are shown below.
