Explanation: dsname is a required
positional parameter specifying the fully qualified name of the data
set you want DFSMShsm to back up. For dsname, substitute
the fully qualified name of the data set.
Defaults: None.
Note: - Because dsname is a required positional parameter, you
must specify it immediately after the command name. You cannot specify
an alias for dsname. If you do, DFSMShsm does not backup
the data set.
- The volume where the data set resides must be mounted before you
issue the BACKDS command.
- DFSMShsm does not handle partitioned data set members individually.
a member name of a partitioned data set, DFSMShsm backs up the entire
partitioned data set.
