•
Specify source and target datasets that differ in position.
•
Specify the source and target datasets that are in the same volume, provided that they
do not overlap.
6. If the T-VOL is set to offline in step 4, set this volume back to online. This step is not necessary
if the ONLINTGT parameter of the FCESTABL command is set to YES.
The FCESTABL command can only be executed once per Version 2 relationship. You cannot
execute this command repeatedly for the same Version 2 relationship.
(page 102) shows an example of how the FCESTABL command is used. In this example, the
FCESTABL command specifies the following:
•
The data on the extent starting from CCHH'01000004' and ending at CCHH'0357000A'
in the source device numbered 4202 is to be copied to the extent starting from
CCHH'13000001' and ending at CCHH'15570007' in the target device numbered
4203.
•
The data on the extent starting from CCHH'02AC0006' and ending at CCHH'02FF000C'
in the source device numbered 4202 is to be copied to the extent starting from
CCHH'18A00000' and ending at CCHH'18F30006' in the target device numbered
4203 (the operation mode for copying is set to NOCOPY mode).

Establishing Version 2 Relationships by Extents Using the DFSMSdss Command
The DFSMSdss command used to process the Version 2 dataset copy operation is COPY DS. For
information about the available parameters for the DFSMSdss command, see
(page 86) .
When the COPY DS command is issued, DFSMSdss checks whether the selected volumes meet
the requirements for use as Version 2 volumes, and automatically determines whether to process
the requested job via the host. DFSMSdss processes the COPY DS command in a few seconds
and establishes the Version 2 relationship simultaneously as it completes the processing. The
completion of this process is not reported to the user.
(page 102) shows an example of the DFSMSdss command for processing the Version 2 dataset
copy operation. In this example, the dataset on the volume numbered FCPY05 is copied to a
volume numbered FCPY06.
