LTO1 & LTO2 is where I had my crossover point.

You can go into the media database (vmchange) & change the media type on
the LTO3 tapes to be the same as your LTO4.  The drives will read &
write these tapes, they'll dumb down to the format automatically.  I
marked mine with a comment that reminded me these were "Honorary LTO2"
tapes so I could identify them later (number ranges also were
different).

Over time, we transitioned the LTO1 tapes out as their data expired (You
can freeze them until expiration if you want to do this).

Subject: [Veritas-bu] mounting lto3 tapes to lto4


we're planning on replacing our LTO3 drives with LTO4s entirely but want
to utilize the many LTO3 tapes that we still have.  The problem that we
have is that Netbackup sees these tapes as different media
types/densities because ACSLS provides it that way and therefore i can't
mount "hcart3" tapes into an "hcart" type storage unit in Netbackup.
Has anyone experienced this and know of a workaround?

thanks.
