DFSMS reporting facilities help you set policies for placing or migrating data onto DASD or tape. With the volume mount analyzer tool, you can print DFSMS reports on tape usage to obtain statistics about how often tapes are mounted or how often tape data sets are used. These reports can help you decide which classes of data you want to store onto DASD or tape and how long you want data to remain in active storage before being moved.
