Are you sure your Hitachi can emulate a FC tape library or are you just guessing ?
Which drives and libraries does it emulate ?
Actually, I will be using the Hitachi LUN presented to the NAS as the source where I will create the virtual tape. I created the default tape library on the DM. I am not sure the Hitachi can emulate tape, but based on my research it appears that I physical device from Hitachi would have be in between the DM and the Hitachi storage in order to do VTL. Which is why I have decided to got with the NAS VTL route. Thanks for your imput!
