Moving data with COPY

You must move data in order to replace storage devices, add storage capacity, and meet storage requirements. DFSMSdss allows you to perform the following data set movements:

Move data sets from old to new DASD.
Move data sets between Storage Management Subsystem (SMS) and non-SMS-managed volumes.
Move data sets off a volume when requiring hardware maintenance.
Move or copy data sets for other purposes.

The DFSMSdss COPY command performs data set, volume, and track movement.

Data sets may move from one DASD volume to another volume of either like or unlike device types. Where like devices have the same track capacity (3390 Model 2 and 3390 Model 3), unlike devices have different track capacities (3380 Model K and 3390 Model 3).

If you copy a full volume or range of tracks, however, the DASD must be of like device type. The user must specify the source and target volumes. This process permits only one source volume and one target volume.
