We opted to logically partitioned the library (within TSM).

Drawbacks are managing 2 scratchpools and having to migrate some stgpools
from one logical library to another.
Haven't had many other problems, apart form that.

As Richard says, the Readme covers options in reasonable detail. You have
to come up with you own conclusions.

Mixed 3592Gen1 & Gen2







Hello all,

   Being more at home with LTOs, I am facing the following. We have a 3494
library with some 3592Gen1 drives. Recently, additional drives were
installed, and they are 3592Gen2. My question is: can TSM identify by any
means that a particular volume was written in Gen2 format and try to read
them only on Gen2 drives? That means that I should (possible answers):

1) Partition the 3494 with one library with Gen1 drives and one with Gen2
drives
2) Use all drives with FORMAT=3592C in the devclass definition (No! No!)
3) Use FORMAT=Drive and let TSM decide what to do

To complicate further: TSM Server is 5.3.4 on AIX 5.3, but I still have
some storage agents at 5.2.3 level, who don't "understand" what 3592-2 is.

Thanks for your advice,
Paul van Dongen
