I guess "MVS" (of all flavors old and new) is a bad design then. SYSDSN ENQs are issued without RESERVE. If it was, no one would ever have been able to share DASD at all without GRS/MIM. Without GRS/MIM there is no data set integrity when sharing across systems. The VTOC itself is protected with a RESERVE (SYSVTOC) so you won't blow that away, but the data sets on the volume are not protected. But if you can live with the exposure (perhaps using security rules limits it), you can share volumes without GRS/MIM because of the fact that a RESERVE is not issued with SYSDSN.
