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 66 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 66 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 67 ). Volume area that is not allocated as a dataset is not copied.

NOTE: If the capacity of the copy source volume is larger than the capacity of the copy target volume,
and if REQUIRED is specified for the FASTREPLICATION parameter, the ADR920I message occurs and the
COPY command will end abnormally. In that case, do one of the following:
NOTE: Select the volume which has the same capacity as the copy source volume, and specify it as the
copy target volume.
• Do not specify the FASTREPLICATION parameter.
• Specify PREFERRED for the FASTREPLICATION parameter.
• Specify NONE for the FASTREPLICATION parameter
