It's not really that hard and fast of a rule


Netbackup doesn't know hcart from hcart2 or hcart3, but whatever type
the drive is must match the configured type of the tape.
If the tape is hcart3 and the drive is hcart2 (regardless of LTO gen)
it's gonna complain.

If you've replaced all of your LTO2 drives with LTO2 drives, then change
the type of all of your old LTO1 tapes to match the type of the new LTO2
drives.....the RFID chip in the tapes should identify the tape type to
the drive with the tape is inserted, and the drive should read/write to
the tape in the proper format based on how the tape ID's itself, not by
the configured Netbackup media format.

hcart1, 2, 3, etc, are just numeric designations....could be DLT, SDLT
or LTO of any generation.
