I was quite surprised to find that NetBckup is not just looking at the tape
label, but also what I think is the cartridge serial number with LTO. I guess
that comes from the LTO-CM. This is 6.5.4
This happened on a Windows Master/Media server in our test lab:

So I'd suggest, don't reuse barcodes.

Subject: [Veritas-bu] LTO tape label / sequence?
Hello,
The question of "should we be paying particular attention of tape labels"
question reared it's ugly head for me once again and I can't remember the
answer.
Am I correct to believe that NBU won't import or confuse itself or the database
if we should put a tape in the robot which has the same label as a tape that's
has already been written too and cataloged?
And, should I be ordering labels with an existing sequence?
Regards,
John Keating
