I've been having a lot of problems with tapes in my tape library lately.

Several media volumes have been getting frozen for a variety of issues, 
so what I was going to do was bplabel them and start from scratch on 
these volume sets. However, several of these tapes come up with the 
following error:

"The requested tape was found to be unmountable on multiple drives"

This behavior follows my removing the media from all media pools and 
from Netbackup as a whole (or so I thought). Then I would reinventory 
the library so these tapes end up in my scratch pool and not in their 
original volume pool. However this error message would stick around, and 
the media server never even tries to mount the tapes. I've tried bplabel 
and even tpreq so I can use mt commands to try and erase and retension 
the tape. In each case I get this error message, which is quite 
fustrating. My next step is/was going to be using the library itself to 
mount the tape in the drive and run the mt command to bypass having 
media manager deal with the tapes at all.

Anyone have any insight or suggestions on how to deal with these tapes? 
I really cant believe that the media is bad, I've only had these tapes 
maybe 4 months and only a handful of them have been used.
