If I understand you correctly, you're saying that the +1 generation gets catalogued if on a disk, but not if on a tape. In a disk SMS environment, the creating of a disk dataset and cataloging thereof causes no problem because SMS usually "initializes" the dataset with an end-of-file. In the case of a tape dataset, the dataset is "initialized" only if an OPEN is done on it. I don't know how it is done, but z/OS does not catalog a tape dataset which was not OPEN'ed. The "solution" is to OPEN the tape dataset. If you can't do it in any other way, you could always use IEBGENER to copy a DD DUMMY (0 records) to the tape. Either with DISP=(NEW,CATLG) on a step before the current step, changing the current step to DISP=(MOD,CATLG). Or on a subsequent step with DISP=(MOD,CATLG). At least, this is how I do it.
