Hi,

AFAIK there are two types of VTLs. The first pretends to be a tape drove 
(that's what the T in VTL stands for after all). and no LVM mirroring is 
possible on tapes (but TSM copypools are!). The other is basically nothing more 
or less than a NFS/CIFS server. ANd I know of no host based mirroring for NFS 
mounted volumes.

Now, I believe that the Protectier falls into the true VTL category.
