Because dsname is a required positional parameter, you must specify it immediately after HDELETE.

When you specify a password with a filter, all the password-protected data sets affected must have the same password. Otherwise, DFSMShsm rejects the HDELETE command for those password-protected data sets that are protected by some other password.

DFSMShsm does not process individual partitioned data set members. If you specify a partitioned data set name with a member name, DFSMShsm rejects the request.
