NB5.1 with mixed LTO3 / LTO4 library

[kfh]

Greetings,
I'm currently using a mixed LTO2/LTO3 tape library using HCART2 and HCART3 to differentiate the tapes and drives.
I'm going to replace the LTO2 drives with LTO4, but NB5.1 doesn't have an HCART4 choice for drive, tape, or library
types.

So can I safely use HCART as the drive type in tpconfig, media type for the tapes, and library type for storage unit definition?

Thanks.

yes

thank you....i was feeling bad enough about the cost of the upgrading of the drives without having to worry about
upgrading my servers to NB6 too.
