When you update the P-VOL and want to give it only to the specified users
(S-VOLs 5 and 6 in the figure), do the following:
1. Create cascaded pairs, and distribute data in the P-VOL. Assign users to
whom you want to distribute the updated data, and users to whom you
do not want to distribute the updated data to separate node volumes.
2. Delete the pairs in the node volume where you assigned users you do not
want to distribute the updated data to (S-VOL 1 in the figure).
3. Update the P-VOL.
