Version 1 copy and star ts Version 1 operations, the COPY FULL command will be completed within a
few seconds, and the Version 1 relationship is established at once. Version 1 data is copied in the
background, and the completion of copy is not reported to the user.

Version 1 can establish a relationship for one volume pair at a time. When you perform the copy
command (COPY FULL) on a volume pair in the F-Copy status that is in the process of the Version 1
copying operation, DFSMSdss identifies the request as an ordinary copy request via the h ost and
performs the copy operations.
