Guys,
The barcode rule works, now making a backup with the new drive. TNX!
Now I have another problem, when I do an inventory of the library, it
stops at slot 525 with a message about not being able to add the media.
Since I didn't install the web access thingy properly I am now going to
visit the library to check if there is something physically wrong with
that slot. Maybe I stuck the tape in upside down?
CU,
Marcel

Marcel,
Let me see if I can make this as easy as possible for you.
You will need to use barcode rules. Hopefully your new labels have a
different range (in particular from left to right) than your current
DLT carts do.
Now, I'll add a couple of additional items. First, you mention that
NBU only reads the "last six positions"... Well, NBU thinks the first
positions are from left to right and therefore the L2 is in fact the
last 2 positions. You are correct though, NBU does in fact use the
last six positions by default. So, I'm assuming that if your media
don't have that L2 (media identifier incidentally), then the library
isn't reporting the L2 to NBU. That's not a big deal since you would
probably just use a MEDIA_ID_BARCODE_CHARS directive to tell NBU to
ignore it. And since barcode rules work from left to right, there's no
"good" way to use the L2 in a barcode rule..... Whew, confused? Hope
not.
So, I'll give an example.
Assume you have existing media that are all DLT media and the barcodes
are AAAxxx. Now when you have the new LTO-2 Media, hopefully they have
something different, lets say BBBxxx range. You need to create a
barcode rule that lists AAA (don't put any wild cards in or it won't
work) and identifies that range the same as your existing DLT media.
Then, you can create a second rule that lists BBB and make it the same
density as your LTO-2 drives (probably hcart).
I hope that helps a bit and doesn't confuse you too much.
