Online backup

To split the Continuous Access XP Journal volume pair with online backup:

You can also use the pairevtwait command, which waits for the pair to be split (PSUS).
pairvolchk : Volstat is P-VOL.[status = COPY] => Splitting
pairvolchk : Volstat is P-VOL.[status = PSUS] => Split completes
