By the way, once we upgraded from a LTO3 tape library who readed only 6 characters from a barcode, to a LTO4 tape library who readed the 8 characters from a barcode.
Since we wanted to continue using both LTO3 and LTO4 tapes, I had to modify the default configuration during the "Configure Storage Devices", so each drive is "hcart3" instead of "hcart" ("hcart" seems to be NetBackup default for LTO4).
Now we have two options:
1) Continue using only 6 characters from the barcodes.
2) Using all 8 characters from the barcodes.
For the 8 character barcodes, we need first to do the following:
a) Insert LTO3 tapes in the library.
b) Logically move each LTO3 media to its new location (new robot, new slot, etc).
c) Rescan/Update Barcode.
d) Repeat from a) for all LTO3 tapes (don't know how to update barcodes without doing an "import").
I wonder if NetBackup will use the LTO4 data cartridges as intended (i.e, 800GB native, etc), even when using the "hcart3" configuration. I guess using LTO3 barcodes on LTO4 tape drives doesn't matter either.
