NOPACKING specifies that DFSMSdss is to allocate the target data set only to the same or like device types as the source data set is allocated on and that DFSMSdss is to use track level I/O to perform data movement. This results in an exact track-for-track image of the source data set on the target volume.

dsn: Specifies the fully or partially qualified names of a PDS to be processed.

NOPACKing is only valid with a PDS. If REBLOCK is specified, REBLOCK is ignored for the data set. If the data set is specified with CONVERT(PDSE()), NOPACKing is ignored for the data set.

A PDS copied or restored by using NOPACKing is not be compressed during data movement.

NOPACKing can be used for a damaged PDS that is currently usable by an application but would be made unusable by compression or other rearrangement of the physical layout of the data.
