If DASD capacity planning (Type C) records are requested, one record is created for each level-0 and level-1 volume for each day there has been activity. For example, if five volumes had DFSMShsm activity for seven days, there would be 35 DASD capacity planning records. The number of days that volume statistics are kept to create these records can be controlled by the MIGRATIONCLEANUPDAYS parameter of the DFSMShsm SETSYS command.
