Was there a secondary message with the dsname? Was this a temporary dataset? An alias? A GDG?
>From >https://www.ibm.com/servers/resourcelink/svc00100.nsf/pages/zOSV2R5sa380675/$file/ieam800_v2r5.pdf#page=149 Explanation The system could not reserve a data set for a job. The type of data set requested and the problem are as follows: • The DD statement requested a non-VIO, temporary, direct access data set. The data set name is the same as an existing system-generated data set name. • The DD statement specified an alias name. After locating the real data set name in a catalog, the system found that the data set is already reserved by another user. • The DD statement requested a generation of a generation data group (GDG). After locating the catalog- generated name for the generation, the system found that the data set was already reserved by another user. • The DD statement requested all levels of a GDG. When checking the individual levels, the system found that one of the levels is already reserved by another user. -- Shmuel (Seymour J.)
