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...
