There's no reason you can't share the library. The 3584 supports partitioning. Unlike in your 3494 where the Library Manager controls what tapes go to what host via category codes, in the 3584 you partition the library into multiple 'virtual' tape libraries, so some slots and drives are visible only to one host, and other slots and drives are visible only to the other host. The virtial library is presented to the host system as a single library with only the number of slots that are available in that partition, with only the drives that are available in that partition, so the backup software doesn't need to understand anything about the competing product.
The only place you have to be careful is when adding/removing tapes from the library. Make sure you're only adding/removing tapes from one server at a time to ensure you don't inadvertently give Veritas tapes to TSM and vice versa, etc.
Shouldn't be a problem, though...

Since there was only one response I think I need to give a bit of info to help with why I'm asking the question.
We have TSM and Veritas here. Not something I wanted but its here. Currently each reside on their own libraries mainly because one is LTO2(Veritas) and the other a 3494(TSM). I'd like to start moving TSM LTO this year. We are in the midst of standing up a DR site and I'm trying to see how we can bundle this together. So instead of standing up 2 libraries I'd like to stand up one large enough to handle both the Veritas and TSM backups. I'd like to add on to what we have here if they could live together nicely.
The 3494 we have is currently shared by the mainframe and 2 TSM servers. We already know we have to bring up a 3494 at the DR site for the mainframe/TSM and another for Veritas. I would like however to send part of the 3494 we have now to handle portions of the TSM backups along with getting hardware for the IBM. If we stood up an LTO library here to start migrating off the 3494 that is doable. I would then need LTO at the DR site for TSM but would like to see if a single large enough unit would suffice.
So my original question is still, can a LTO library be shared by both systems provided they each have their own dedicated drives? Has anyone done this or think it can be done?
Any information, be it in the form of links to articles or direct knowledge would be greatly appreciated.
Thanks,
Geoff
