and the T-VOL in the same way as when the relationship was created.

the processing. The completion of this process is not reported to the user.
The following first example shows the DFSMSdss command for processing Compatible FlashCopy
volume copy operation. The second example shows the COPY FULL Command (FCCGFREEZE)
and the last example shows the CGCREATE Command.
