You can forward or reverse resynchronize Thin Image pairs. A forward resynchronization resynchronizes the S-VOL from the P-VOL. A reverse resynchronization restores the P-VOL from the S-VOL.
Forward resynchronization
You can use the Normal Copy (Primary > Secondary) method to forward resynchronize pairs.
This method performs a full forward resynchronization of data from the P-VOL to the S-VOL. The differential data is copied to the S-VOL.
Reverse resynchronization
You can use the Reverse Copy (Secondary > Primary) method to restore pairs.
This method performs a full restoration of P-VOL data from the S-VOL.
