Because there's software in the VTL that emulates tape drives. To TSM it's just another tape library.

In order to do that wouldn't the VTL have to have some kind of similar code as Sanergy and then the question is does that play nicely with TSM. Or am I missing something really obvious here? Please explain how you will get Lan-Free to work in a TSM environment without the Sanergy code. Thank You. -- Regards, Mark D.
