Good Morning Sergey,
The answers are it depends.
You have to make sure that you do not have the system try to
load a LTO-3 tape into a LTO-2 tape drive.
A simple method if you have the IBM 3584 tape library is to
define a new virtual library for the LTO-3 tape drives and treat them as two
libraries in netbackup. That is a new storage unit, and the lto-2 and lto-3
tapes and tape drives would have different media settings (for example hcart2
and hcart3).
We have not tried it yet, but it would seem that one could have
one virtual library with two different storage units with the tape drives and
tape media set to different media settings. One would also require bar code
rules to assign new tapes to the correct media settings. I am guessing that
this would require different volume pools.
It would be nice if netbackup could handle the fact that the
tape drive can write to two different media types, and read three different
media types.

Subject: [Veritas-bu] Different drive types with one robot
We
have IBM tape library with LTO-2 drives and planing to add LTO-3 drives and
LTO-3 tapes to it.
How
to configure netbackup infrastructure to use different drive types with single
robot?
Does
Drive wizard detect new drives correctly or we need add drives
manually? Is new volume group fot LTO-3 needed for
tape operations?
Thank
you very much, Sergey
