If you selected volumes of different media types or volume residences, a Move Volumes dialog box appears for each residence and each media type.
For example, you select two full volumes to move out of a robotic library and two stand-alone volumes to move in as replacements. A dialog box appears for the two full volumes and another dialog box for the two replacement volumes. In this example, complete both move dialog boxes to perform the move (complete the move for the volumes that are full first).
