an optional parameter specifying the type of unit where DFSMShsm can
allocate the nonmanaged source volume.
For unittype, substitute the type of unit where DFSMShsm
can allocate the volume.
The following are valid types of DASD units:
Defaults: None.
Note: - You must specify the UNIT parameter if the volume you specify
is not managed by DFSMShsm.
- DFSMShsm ignores the UNIT parameter if you specify the MIGRATIONLEVEL1
or DATASETNAME parameters.
