Hi,
Update the deviceclass to new library is the key. But it is important you
verify if the label of tapes are the same in both libraries but Tsm thinks the
tapes are scratch.

Asunto:Re: 3584 questions
What Thomas said, only I think he meant to say "3584" everwhere he said
"3484". AFAIK, there is no such thing as a 3484.
We did a similar thing moving from an ADIC Scalar10K SCSI library to a 3584.
As long as the new library has the same library name as the old library, TSM
will be fine.
