You can, of course create fake virtual disks using the scsi_debug
"host". I use it all the time for testing various scenarios. The only
problem is that there are only virtual devices connected to scsi_debug. I
suppose what you could do is create a second virtual device in scsi_debug
which the scsi_debug adapter remapped to a live device elsewhere...
