Both DFSORT and SYNCSORT make use of primary and secondary space allocations (up to the z/OS legacy 16 extents per volume) but for only the first volume - there is not VOLADD processing taken.
Also, if SORTWKxx DDs are hardcoded, then you must also have the DSNTYPE=LARGE (either explicit or via DATACLAS) to get past the again-legacy 1439 cylinders (equlvalent), again but only for the first-volume and without VOLADD. Otherwise if you omit SORTWKxx DDs and allow the host sort package to do its best to estimate input data records/size volume, then you automatically get DSNTYPE=LARGE via dynamic allocation means.
