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. > Thank you, > Mehdi -- Met vriendelijke groeten/Kind Regards, Remco Post [email protected] +31 6 248 21 622
