Swap&Freeze Option
The Swap&Freeze option allows the S-VOLs of a Business Copy pair to remain unchanged after the
quick restore operation. If the quick restore operation is performed on a Business Copy pair with the
Swap&Freeze option, update copy operations are suppressed, and are thus not performed for pairs in
the PAIR status after the quick restore operation. If the quick restore operation is performed without
the Swap&Freeze option, the P-VOL and S-VOL are resynchronized when update copy operations are
performed for pairs in the PAIR status.
Note: Make sure that the Swap&Freeze option remains in effect until the pair status changes to PAIR after
the quick restore operation.
Figure 9 on page 28 shows the state of the S-VOL after the quick restore operation with or without the
Swap&Freeze option.
