John, Make sure your TAPESPANSIZE is adjusted for your tape size. Also make sure that you have TAPEUTILIZATION set properly. Just a couple of thoughts about things that can affect tape usage. We are at 1.9, and use an IBM ATL with 3592 drives, and are not seeing this issue.

And it could be happening to you unless you monitor it. We have SETSYS PARTIALTAPE(MIGRATION(REUSE) BACKUP(REUSE)) set in ARCCMD00 but when AUTOBACKUP uses a scratch tape, the following happens. IEC501A M 8701,PRIVAT,SL,COMP,DFHSM,DFHSM,HSM.BACKTAPE.DATASET IEC705I TAPE ON 8703,M00812,SL,COMP,DFHSM,DFHSM,HSM.BACKTAPE.DATASET,MEDIA4 ARC0120I BACKUP VOLUME M00812 ADDED, RC=0000, REAS=0000 IEC205I SYS18542,DFHSM,DFHSM,FILESEQ=1, COMPLETE VOLUME LIST, 497 DSN=HSM.BACKTAPE.DATASET,VOLS=M00812,TOTALBLOCKS=2 ARC0421I BACKUP VOLUME M00812 IS NOW MARKED FULL We only noticed this because we are short on scratch tapes, 'cuz the OPS manager only orders them when we run out. After going to zOS 1.08 we suddenly went from 5-10 scratches being used for hsm backup to 150+. If you have a large ATL and lots of scratch, this could be happening to you right now. The tapes get returned after RECYCLE and RMM daily job, but ATL gets beat hard. We are HOLDing the BAckups until we get this fixed. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
