You might try - with 1 or 2 tapes at a time to see if it works?
Deleting the unassigned barcode tape's to be used with the new drive.
Use the Add new volumes function to add them back in - but ensure that the
Type of media is different than all of the others used for the other drives.
Then Ensure that the DRIVE TYPE on the new drives is the same as the Volumes

That you just added as Type - "Must be different than the old / other
drives" but the same as the tape type's you just added.
Then The Storage Unit that you use for those tapes / drives must be
different than the old drives. Storage unit = The same type as the drives
and tapes.

Or most of the above and using the vmchange -new_mt  on tapes already
unassigned in the robot.

When restoring data the type specified on the drives must be the same as it
was specified during the backups - As I learned at a Disaster recovery
mission at Sungard in New York.

You should be able to setup a barcode rule that says:

BUP0 - HCART
BUP1 - HCART
BPU2 - HCART
BPU3 - HCART
<default> HCART2

so the new additions are marked as LTO2.  I say "should be able" since I'm
doing this and my last injection all injected as 8mm, despite the barcode
rule.  I'm not sure it's working right.

Once injected wrong, the "vmchange" command is an easy way to change it to
what you want.

They are not duplicates, just in the same range. So BUP000 to BUP399 are
DLT, BUP400 till BUP599 are LTO2.

It sort of works now for most tapes. Still investigating what causes
some of them not to work.

I know that next time I'll buy a complete new library in stead of
putting different drives in one.

Duplicate Barcode labels just reared it's ugly head here, and caused
some
pretty major problems between my media and master server.  I kept
running
out of media, and couldn't figure out why.  If you have duplicates in
your
library, your media server cannot update the volume db on the master
server,
because it fails with the duplication error.  We had some really major
problems, and I'm surprised it didn't blow up before.  Removing the
tapes
solved the problem... But it was bad for us because we had well over 20
dupe
tapes. :O  My recommendation would be to avoid this at all costs!

Hope this helps!

Jen

I'm not sure you can get away with having duplicated barcodes.
Minimally,
the Media ID must be unique.  The barcode is technically a different
field
in the volume DB but is usually the same as the media ID.

Look at the output of vmquery -w -m <tapenum>.  First field is media ID,
fourth is barcode.  They're usually the same.  You're just asking for
trouble if you try to duplicate barcodes despite the difference in tape
type.

K,

Thanks for the reply. We have 'L2' on the barcode too, but somehow
Netbackup
still recognizes it as DLT. Probably because it only reads the last six
positions of the barcode, so it will not see the 'L2' part.
Does that sound logical? Maybe this will work better if we add the
latest
device mapping file?

On the other hand, you say your library determine the type itself. Hmm,
I
wish ours would. I will have to re-read the manual.

On using barcode rules: unfortunately we chose to have the labels for
the
LTO2's in the same range as the other labels. So it's hard to design a
rule
that picks out the LTO2's based on the barcode.

CU,

Marcel

i use barcode rules to make sure certain barcodes end up in diff pools,
others may do some more fancy things.  we use a stk l180 and we have on
the
barcode (not part of the barcode) 'L2' for the lto2 tapes so that the
library itself will know what type of tape is in the slots.  the stk
barcode
scanner will use this part of the label to determine the tape type, ie
dlt,
lto, etc...
