I assume by lto; you mean LTO1?
If so they will be write protected because and LTO3 drive cannot write to lto1 
tapes, but it can still read them.

Google LTO

Subject: [Veritas-bu] can't re-use older tapes with new library


Here is the problem.  Some time ago we upgraded a library from an lto to lto3.  
Now they scan differently and I set barcode rules to get the tape numbers to 
match.  The problem is that the older tapes are showing up as write protected.  
I assume this is because the media id and the id that netbackup puts on the 
tape do not match.  I have tried to use re-label with both gui and command 
line.  I can't figure out how to get around this one.


p.s.  None of the data on the tapes is needed.  We just don't want to throw 
away hundreds of LTO tapes.
