Thanks, this is encouraging. (We're still trying to figure out a non-disruptive non-chaotic way to test with SMS on for tape.) If we run this step for DASD
// EXEC PGM=IEFBR14 //SMSDSN DD DISP=(NEW,KEEP),DSN=any.SMS.name,UNIT=SYSALLDA,... the data set gets cataloged even though not requested. Then a second run of the same step then fails because of dup name in the catalog. If this step can be run multiple times with UNIT=TAPE, then I think we'll be fine. Again, we don't know how common this practice is, but we don't want any nasty surprise. . .

And though we use an ICF catalog for our meta data (tape volume and tape library-related information) we do not require that the tape datasets on an SMS-managed volume be cataloged. This is where we differ from SMS-managed disk where the datasets are cataloged. And with SMS-managed tape, the ACS routines and constructs are then used to manage the tape volumes and tape libraries. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
