NOTE: FlashCopy Mirror Version 2 supports VSAM datasets. However, when the user specifies attributes
for the copy source extents that differ from those specified for the copy target extents, DFSMSdss invokes a
different program (such as IDCAMS), and, as a result, FlashCopy Mirror Version 2 may not be able to use
VSAM datasets. For further information, please refer to the IBM user document mentioned above.
Creating FlashCopy Mirror Version 2 Pairs by Volume Copying
The DFSMSdss command used to process FlashCopy Mirror Version 2 volume copy operation is
COPYFULL. When the COPYFULL command is issued, DFSMSdss checks whether the selected volumes
meet the requirements for use as FlashCopy Mirror Version 2 volumes or not, and automatically determines
whether to process the requested job via the host or not. DFSMSdss processes the COPYFULL command in
a few seconds and establishes the FlashCopy Mirror Version 2 relationship simultaneously as it completes
the processing. The completion of this process is not reported to the user.
Figure 54 shows an example of the DFSMSdss command for processing FlashCopy Mirror Version 2
volume copy operation. In this example, the entire data in a volume numbered FCPY05 is copied to a
volume numbered FCPY06.
Figure 54 Example of DFSMSdss Command (COPYFULL)
When DFSMSdss command “COPYFULL” is executed, all the datasets on the S-VOL are copied to the
T-VOL (see Figure 55). Volume area that is not allocated as a dataset is not copied.

Creating FlashCopy Mirror Version 2 Pairs by Dataset Copying
The DFSMSdss command used to process FlashCopy Mirror Version 2 dataset copy operation is COPY DS.
When the COPY DS command is issued, DFSMSdss checks whether the selected volumes meet the
requirements for use as FlashCopy Mirror Version 2 volumes or not, and automatically determines whether
to process the requested job via the host or not. DFSMSdss processes the COPY DS command in a few
seconds and establishes the FlashCopy Mirror Version 2 relationship simultaneously as it completes the
processing. The completion of this process is not reported to the user.
