Is it possible there is some competing "service" that forces drive maintenance (head cleaning?) every xxx tape mounts?
An RMM feature? -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Tony Thigpen Sent: May 4, 2018 12:35 PM To: [email protected] Subject: unexpected tape issue with RETAIN I have a 50+ step backup job (using real 3590s) that has steps like: //STEP049 EXEC PGM=ADRDSSU //SYSPRINT DD SYSOUT=* //DASD DD DISP=SHR,UNIT=3390,VOL=SER=HKYTD4 //BACKUP DD DSN=DR.T.DSS.HKYTD4.&SUF,DISP=(NEW,KEEP,DELETE), // UNIT=3590,VOL=(,RETAIN,REF=*.STEP048.BACKUP), // LABEL=(49,SL,RETPD=&DAYS),DCB=(MODEL.DSCB,BLKSIZE=0) //SYSIN DD * DUMP FULL INDD(DASD) OUTDD(BACKUP) ALLD(*) ADMIN TOL(IOER) ALLE /* //* //STEP050 EXEC PGM=ADRDSSU //SYSPRINT DD SYSOUT=* //DASD DD DISP=SHR,UNIT=3390,VOL=SER=HKYTD5 //BACKUP DD DSN=DR.T.DSS.HKYTD5.&SUF,DISP=(NEW,KEEP,DELETE), // UNIT=3590,VOL=(,RETAIN,REF=*.STEP049.BACKUP), // LABEL=(50,SL,RETPD=&DAYS),DCB=(MODEL.DSCB,BLKSIZE=0) //SYSIN DD * DUMP FULL INDD(DASD) OUTDD(BACKUP) ALLD(*) ADMIN TOL(IOER) ALLE /* This job always worked on OS/390 2.10, but under z/OS 1.13, randomly, when going to a new step, it wants the current tape mounted on a different 3590. Additionally, it does not unload the tape from the first drive. Also: If I have only one drive online, it runs to completion. If I have two drives, but the other one is busy, it runs to completion. Info: This system is using RMM as a tape manager, but the files being created on the tape are not defined in any storage group or RMM. It is driving me batty. I have to be 'not seeing' something. -- Tony Thigpen ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
