single copy source area when seven or less multi-copy sessions are already set.

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 per-
formed.
