Subject: Re: SCSI Tape to TAP utility

On the Honeywell we had a Tape Management System that managed the tapes. All the tapes

the operators which tape number to mount. It would also manage the scratch pool of expired
tapes and tell them which tapes to have ready for new outputs. It also managed off site
storage. We trusted it and never removed a write ring. If you mounted a tape with current
data the system read the label and dis-mounted the tape....

If you had a tape master file then typically that
had the same dataset
name on the master in and out....
But obviously, not the same VSN...
There's (potentially) a lot of information in a set of labels, particularly if any
of
the user labels are used.
See, for example, this CERN document:
