As a further answer from before on how to keep LTO1 tapes
from being used in LTO2 drives.

The DEVCLASS forLTO1 tapes has a parameter called MOUNT LIMIT.
If you say have 6 LTO1 drives and 4 LTO2 drives, then set the
MOUNT LIMIT of your LTO1 devclass to 6.  That, I believe generally
prevents LTO1 tapes from being used in LTO2 drives.  As I think
LTO2 drives are only used by LTO1 tapes, if ALL LTO1 drives are
in use AND the MOUNT LIMIT exceeds the number of LTO1 drives.

Not sure if that takes care of 100% of the cases and not sure
if this would be the correct scenraio for all types of
libraries/drives.

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?
