I've gotta ask Geoff,

Why, with a 3494 and LTO library would you move TSM to LTO? My first option
would be to move veritas to the 3494.

3494 is industrial strength and plays well in multi host and multi
application environments.  Use 3592 drives and you'll have capacity to burn.
Also,  second-hand frames to provide additional storage are quite
economical.  Second-hand is viable here - what can go wrong with a dumb
storage rack? and you'll have no trouble getting IBM maintenance coverage
for it if that is important to you.

Regards

Steve.

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
