HI DUDE!  Happy New Year!

Sounds to me like that will work.  TSM will certainly let you have
multiple devclasses pointing to the same library.

I would just test it - update the devclass, check a cartridge out of
your 3583 library, check it in to the 3584 library, see if you can run
AUDIT.

BUT, I don't see how your offsite tapes are an issue - you're never
going to WRITE to them again on those LTO3 drives.
So won't the appropriate action be to do MOVE DATAs from the 3583 LTO1
carts to the 3584 LTO3 carts?

Or are you planning to keep the LTO1's in the 3584?  In that case you
have to partition the library, anyway?

Subject: Question on combining libraries


TSM Server 5.3.2.1 running on AIX 5.3
3584 library (3584CLASS)
3583 library (3583CLASS)

We have 2 libraries (3584 and 3583) each with 4 SCSI LTO-1 drives. We
are purchasing 6 LTO-3 fibre drives that will be installed in
the 3584 only! The wish is to take the 3583 out of the picture. If after
swapping out the drives can I just change the 3583CLASS
device class to point to the 3584 library and then I would have 2 device
classes referring to the same library. Or would I need to
create all new stgpools that reference only the 3584 library? I don't
really want to do that as all my offsite tapes (100's of 'em!)
use the 3583CLASS.
