To initialize the new volumes, use ICKDSF. See the IEACLNIN job in SYS1.SAMPLIB.

The size and location of the VTOCs specified will be changed on some of the new volumes by full-volume copy operations when sizes and locations of the VTOCs on the volumes they are copied from are different. The VTOC size and location remains as specified for new volumes that are not copied using full-volume physical copy.
