FLASHCPY ESTABLISH UNIT(X'7000') TARGETVOL(X'00',X'01',7001) CHANGERECORDING(YES)
By using Fast Reverse Restore, the S-VOL becomes a T-VOL and T-VOL becomes an S-VOL,
and then the data of the resulting S-VOL is copied to the resulting T-VOL in the following ways:
•
If the S-VOL was updated before performing Fast Reverse Restore, Fast Reverse Restore
copies only the updated data from S-VOL to T-VOL.
•
If the T-VOL was updated before performing Fast Reverse Restore, Fast Reverse Restore
copies the updated data from the S-VOL to the T-VOL.

for this parameter and
COPY for the MODE
parameter, the relationship
will be maintained even after
the background copying

the differential data between
the S-VOL and the T-VOL will
be managed. As long as the
relationship is maintained,
you cannot update the
T-VOL.
The differential data
between the S-VOL and the
T-VOL will be copied when
you execute the FCESTABL
command with
