Is anyone using multiple tape/tape drive formats in one library with a
single media server?
=20
for example:
=20
one server, one library
some LTO2 drives, some LTO3 drives.
=20
how do you manage it? can't (from what I can tell) assign each type of
drive to a different storage unit (without a second media server).
Do you have both types of tapes, and let NBU assign jobs and tapes to
drives as it pleases?
=20
I want to avoid my LTO2 tapes being loaded into LTO3 drives and being
written so that they can no longer be used in an LTO2 drive.
=20
Also, I'd like to send slower (100mb/s) clients to LTO2 drives, and GigE
clients to LTO3, etc.
=20
best way I can see to do that is to add another library for the LTO3
drives, so that there's a separate storage units with just those drives,
OR add a second media server, and configure zones to allow each media
server to only see one type of drive.
