For those of you who have made the leap to Virtual tape libraries:

I don't see any of these devices on the TSM hardware support page; 
do you just base your "TSM support" on the device type that the VTL
emulates?

And has anyone run into problems with a VTL that have to be resolved by
the VTL vendor?
Any kind of SCSI errors, or problems other than replacing physical
disks?

Thanks!
