dsname: Specifying the name of the data set being altered
Explanation: dsname ... is a required positional parameter specifying the fully qualified data set name or list of fully qualified data set names of the non-SMS-managed data sets whose backup attributes are being changed.
Defaults: None.
Note:
- Because dsname ... is a required positional parameter, you must specify it immediately after the command name.
- DFSMShsm does not handle partitioned data set members individually. If you specify a member name of a partitioned data set, DFSMShsm changes the backup parameters for the entire partitioned data set.
