GLESL790E The mmbackup option does not work with a plain file list, or all of the files in the list are not yet backed up.

Explanation
            The input file list is in plain format or empty. This can also happen when all of the files in the GPFS scan file are filtered out because they are not yet backed up.

        
Operator response
            Provide an input file list that is in the GPFS scan file format, or run a backup before the migrate operation.
