A DFSMShsm QUERY command was issued with the SETSYS parameter. The maximum number of recycle tasks allowed to process concurrently is ytasks. When processing backup tapes, the input drive is deallocated for every bfreq recycled connected sets, per task. When processing migration tapes, the input drive is deallocated for every mfreq recycled connected sets, per task. If either bfreq or mfreq is zero, then the input drive is not deallocated during recycle processing of that category.
