When it comes to LTO3 to LTO4 conversion, what about the catalog? I
found where to control what tapes are used for Media 1 and Media 2 (and
reside in the Netbackup pool) but I assume I can leave these on LTO3

Yeah that is our intent, to keep the media type the same. Changing drive
types presents a more challenging rollback and also limits us to the
amount of drives we can us during the migration and for restores.

Nate,
If your library is not checking the suffix for tape density, the
barcode label doesn't really matter. It should figure out what
density the tape is when it looks at the tape and will write
accordingly. I did this at one point because our gen 3 tapes labels
came in with "L2" on the end. We
I've heard mixed reports from people varying from "it works, but will
result in bad things" to "it will not work, period" when it comes to
mixing labels on media types. The issue we face right now is we need to
order more tape, and would rather not order LTO3 when it will just be
pitched anyways, b
Nate,
Generally people don't like mixing media levels within a pool but it
can be done within the read/write compatibility between generations.
You may need to keep an eye on your barcode labels and your tape
library. Most libraries allow the barcode scanner to use the last 2
charactors of the la
Thanks for the info on the spec. I was under some impression that
Netbackup (remember, we're on 5.1 here) had an issue with using three
different media types. Maybe this is not the case but it was something I
had in my head. If this is not so, it sounds like we can move to LTO4
fairly quickly.

The LTO spec says the drives should be able to write to media one generation
back, and read two generations back. So an LTO4 should be able to read and
write to LTO3 media, and read from LTO2 media.
Like Jeff said, use barcode rules to assign the LTO2/3 tapes to a different
media type and/or volum
Are you saying we can have LTO2/3/4 all active in the same library? I
was under the impression we couldn't start using LTO4 tapes until we
phased out the LTO2 tapes?

If all you need to do to migrate to the new media is scan them in the
library and assign them to the correct media pool.
The gen4 drives will be able to write to the gen3 tapes and read from
the gen2 if you need to do restores. If you plan on phasing out the
older media when they expire you might
The drives are currently LTO4, the tape is LTO2/3. All we need to do is
migrate to LTO4 media.
