Note that when the Consistency mode is used, a multi-copy from a single copy source area to two or more copy
destination areas in a single copy destination storage system cannot be performed. Even though multiple multi-
copy destinations cannot be set in the same storage system, a multi-copy from the same copy source area to
different copy destination storage systems can be performed.
