When DFSMShsm selects a device type for recall or recovery of non-SMS direct access (DA) data sets, it selects the same device type as the original level 0 device type. DFSMShsm ensures the addressability of the recalled or recovered data by moving a track image copy of the data.

However, a user can issue a DFSMShsm command to direct a data set to a device type that has a smaller, larger, or the same track size. When the user directs the data, however, the addressability of that data depends on how the user tells DFSMShsm to move the data (relative track or relative block addressing) and the access method used by the application program. For more detailed information about recall or recovery of (DA) data sets, refer to z/OS DFSMShsm Storage Administration.
