Drive cleaning issue

Setup is a IBM3310 tape lib. and a ProtecTier VTL.

Master/Media is a Windows server 2008 R2

Running Netbackup 7.5.0.6

All backups first go to the VTL, then are duplicated to the IBM tape lib.

I can't clean drives though Netbackup it always fails with a error 96.

So i clean the drives though the protecTier.  But I have two drives that always say they need cleaning.

Now I just cleaned this on the ProtecTier have reset the drive to bring them back up but after 1 tape load the drive goes down again wanting to be cleaned.

What do I need to do to get Netbackup to see the drive was cleaned.  If I look on the ProtecTier side everything looks fine.  Tape is ejected but on the netbackup the drive shows down.
