Note: There are several DASD models of this disk device. For all of them, the space requirement and file location for z/VSE are the same. Environments B and C include an enlarged Page Data Set (512 MB total size for environment B, and 2048 MB total size for environment C). UNUSED SPACE and END.VTOC depend on the model of the disk device you use and on the size of the Page Data Set. Remember that it is recommended to place the VTOC in the middle of the disk device.
