Be very careful running DFDSS to delete uncataloged datasets. Make certain you understand the complete catalog structure. I would not be surprised to see that "uncataloged" SYS1.* datasets are actually active and in use on other running systems.

Do the volumes look like previous 'sysres' volumes? My 2 cents, take some time to investigate the date and contents, might be you don't want to trash them yet. On the other hand, if you are sure you have the ability to recover your running system and do know what your fall back system is them, blast away. Just my 2 cents..
