         I have 3590E and 3592 drives in my 3494 and have to define 2
logical libraries to the TSM server. Both of them use the same
/dev/lmcp0 device.
        It works just fine, but I had to adjust many of my automation
scripts to work with 2 libraries, as we've always had just 1.

Has anyone tried creating 2 TSM library definitions on the one physical
library address?.
I've done that with ACSLS libraries, and I believe you can do it with
3494 libraries...

My fix was to set all LTO2 tapes as scratch and all LTO1 tapes as
'private'. I then assigned specific volumes from the LTO1 set to the
storage pools I wanted them in. It took about a week to get the LTO1
pools balanced. Be warned if you do this that a) database backups can be
to specific volumes but the deleted backup volumes will be set to
'scratch' and not 'private' (under TSM 5.1.6; may differ in more recent
versions) and b) that TSM will grab the lowest numbered volume in the
scratch pool when it needs another scratch tape.

Happy New Year everyone,

It is my understanding that the TSM server version 5.2 allow you to
manage IBM 3584 library without physically partitioning into logical
libraries to
use both LTO1 and LTO2 drives.   If the library is physically
partitioned
logically into two separate libraries then I can see how  LTO1 and LTO2
can be configured to only to use the LTO1 tapes into LTO1 drives and
LTO2 into
LTO2 drives.. since the TSM server will have two device names like
smc0/smc1 and multi  device classes can be created.

My question is this... if IBM 3584 is not partitioned and configured
with TSM server 5.2, but still wants to use both LTO1 and LTO2 but keep
them separate how can this be done? How does TSM ensure that the LTO2
tapes are only mounted in LTO2 drives and /or LTO1 tapes are only
mounted in LTO1 drives?
