It would not be a problem even if volume does not match barcode.
Have a try : load barcode ABC001 on a volume, label it. In media db,
volume label=ABC001, BARCODE=ABC001.
Now, change barcode ABC001 to BCD002.
Inventory slot. (even with nsrjb -IIEv)
Networker will detect BCD002 is not known in media db and will display
BCD002 and volume name as "*" in nsrjb's output.
Inventory slot, it will mount the tape and adapt
VOLUME=ABC001 BARCODE=BCD002.

If Tape is required for recovery, it will ask "Waiting VOLUME ABC001...."
until tape is correctly inventoried, whatever the barcode may be...

Cheers

I was worried that if I inventoried a slot, and the actual tape label did
not match the barcode label, then the tape wouldn't mount. But that should
only be a problem on relabeling tapes (which at the moment we are not
doing), so I was worrying needlessly.
