Execute the FLASHCPY ESTABLISH command, specifying the RESTORE parameter and reversing the
S-VOL and the T-VOL.
If the S VOL before performing Reverse Restore is updated, only the data of the updated part of the S VOL

performing Reverse Restore is updated, only the data of the updated part of the T VOL will be copied from
the S VOL after performing Reverse Restore.
Note: Set the CHANGERECORDING parameter to YES to maintain the relationship after copying process
is completed and to manage the differential data between the S VOL and the T VOL. If
CHANGERECORDING parameter is not specified, the relationship will be deleted after copying process is
completed.
