Um... there is no such thing as HCART4. You have to decide whether you're
going to define your LTO-4 drives as HCART3 (and risk getting all your LTO-4
media frozen when NetBackup puts it in an LTO-3 drive) or define your LTO-4
drives as HCART (and not get
 to use LTO-3 media in them). No, neither of those
is attractive, which is why getting the new physical media types
("eventually"), which functions along a drive and media capability
model rather than just generational tiering (Can a drive read this media? Can it
write it if it's blank? Can it append to it at the current density (think
IBM media types)? Can it encrypt to it?), but don't hold your breath.

As for the original poster, NetBackup labeled that media as DLT because
that's what your barcode rules told it to do. Go fix those.

Is your LTO3 drive of type 'HCART3'?  And your LTO4 drive of type
'HCART4'?

Inventory is just done with barcodes.  Do you have a barcode rule so
that your LTO4 media is brought in as type 'HCART4'? (or whatever type
you
have set your LTO4 drive to).

For instance my DEFAULT rule brings in tapes as HCART3, but I have a rule
for cleaning tapes that brings them in as HC3_CLN.
