We have a -B10. The magic word is "BVIR", at least for the -B10. That is a way to send "commands" to the VTS control software. On the -B10, the step below will create a DSN on a virtual tape (defined in the DD) which will contain a map of which physical volume contains which virtual volumes.
//STEP0001 EXEC PGM=ICEGENER //SYSPRINT DD SYSOUT=* //SYSIN DD DUMMY //SYSUT1 DD * VTS BULK VOLUME DATA REQUEST VOLUME MAP /* //SYSUT2 DD DSN=&SYSUID..VIRTUAL.TAPE, // DISP=(NEW,CATLG), // RECFM=F,LRECL=80,BLKSIZE=80,TRTCH=NOCOMP, // UNIT=VTS2, // LABEL=RETPD=1 //* //FETCH EXEC PGM=IEBGENER //SYSPRINT DD SYSOUT=* //SYSIN DD DUMMY //SYSUT1 DD DSN=&SYSUID..BVIR.TAPE,DISP=OLD //SYSUT2 DD DSN=&SYSUID..BVIR.ONDISK, // DISP=(NEW,CATLG), // UNIT=SYSDA,SPACE=(TRK,(20,10),RLSE), // BLKSIZE=32760,RECFM=U I don't know if that will work for a -B20 or not. The "control statements" might be different.
