Well I thought that but see a bit above:

 

\\.\Tape1, drive serial number HU10606CNF, expected serial number HU10606CNF

 

 

That’s the drive serial number.

That serial number is actually the drive serial number.  It will freeze media if it gets any error or non matched info

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.

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?
