Yes, call it whatever you want.  Either manually or with barcode rules,
bring your new LTO4 media in as hcart.  Make your LTO4 drives also
hcart.  If your LTO3 drives and LTO3 media are both hcart3, NetBackup
will only put hcart3 tapes in hcart3 drives, hcart into hcart, 8mm into
8mm...

Unless I'm having a memory parity error--always possible--I used to run
5.x (at least, probably earlier), a scratch pool and two drive types
with corresponding media.
