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
