If you select Only P-VOL when creating a pair, the data set that is updated by CFW in the
P-VOL cannot be used in the S-VOL. To use this data set in the S-VOL, release the pair and
format the data set.
This field displays only when the P-VOL is selected.
Shows whether the main system will suspend the pair if the remote system cannot run DFW
