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...

Subject: [ADSM-L] TSM/Veritas on the same library
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
