The 3583 with LTO-2 drives will read/write the LTO-1 tapes, too. Just define
the new 3583 library/drives/paths and then point your 3581 devclass to the
3583 library. Load your LTO-1 storagepool tapes in the 3583 as private, mark
them read-only for restores. Then checkin your LTO-2 tapes as scratch. You
can then do move data commands on the LTO-1 tapes, or just let them go away
by expiration. This way you're up and running WITH your data for restores in
less time.

Subject: Data Migration 3581 -> 3583


Fellows,

I've faced the following situation: a customer has a 3581 Tape Library  (LTO
1) where is defined its storage pool's. It intends to adquire a 3583-L72
(LTO 2). Its TSM server (5.2.2) is running on a Windows 2k server xSeries
232. I gues it's possible to connect the two libraries to the TSM server
(there are sufficient interfaces). My questions are:
- Which is the best way to migrate (move) the data from the old 3581 (LTO1)
library volumes to the new 3583-L72 (LTO 2) volumes? On the top of my
reduced knowledge, I guess that a simple MOVE DATA, followed by some COPY
GROUP changes will solve this problem.
- If it uses the old LTO 1 cartridges on the new 3583 library (I know it's
not interesting), is there a way to make the migration easier?

Regards
