Re: Is it Possible????

Jamie,

"CAN YOU SHARE A TAPE LIBRARY WITH TWO STORAGE POOLS AND DISTINGUISH BETWEEN
DIFFERENT VOLUMES?"

We do exactly that.

We have a 3570 set up as a single library.  We defined two primary tape storage
pools on top of it.  ADSM tracks volumes by pool membership, so when either pool
needs a scratch volume, it asks the library for a tape from the library's supply
of scratch tapes.  Then ADSM places that tape, by name, in the pool that issued
the request.  We then pull tapes using the Move Media command keyed by storage
pool.  ADSM has never confused volumes in the two pools.  Works aces.

Now if you want to route data onto a particular tape, that is a bit at odds with
ADSM's philosophy (you're working for the machine rather than vice versa) but I,
too have had limited need to do that.  My technique is to checkout (but not
remove) all but the target volume, let the job run - which MUST use the
remaining tape, pull that tape at the job's conclusion, and check the other
tapes back in.  Ugly, and I'm glad there's only 19 tapes and I only have to do
that once a year.

Can someone tell me if this situation is possible?

I have 1 3570 tape drive setup( the second half of the
tape drive) as a automated library.  I have this setup
and running to where migration from the PRIMARY
BACKUPPOOL migrates off to scratch volumes in the Tape
library.  Is it possible to initialize a tape under
the same library where the ARCHIVE pool migrates off
to a specific tape in the library TAPE#xx.  I guess my
question is CAN YOU SHARE A TAPE LIBRARY WITH TWO
STORAGE POOLS AND DISTINGUISH BETWEEN DIFFERENT
VOLUMES?  If this is possible HOW???????


Thanks
