You can store data on secondary storage devices, such as a direct access
storage
device (DASD) or magnetic tape volume. The term DASD applies to disks or to
a
mass storage medium on which a computer stores data. A volume is a standard
unit of secondary storage. You can store all types of data sets on DASD but
only
sequential data sets on magnetic tape. Mountable tape volumes can reside in
an
automated tape library. For information about magnetic tape volumes, see
z/OS
DFSMS Using Magnetic Tapesz/OS DFSMS Using Magnetic Tapes. You can also
direct a sequential data set to or from spool, a UNIX file, a TSO/E
terminal, a unit
record device, virtual I/O (VIO), or a dummy data set.
I trust you don't dispute that publication as a final authority. Or would you
care to suggest an alternative? Or submit an RCF?
