Dave.. AFAIK, LTO3 will surely read LTO2 and LTO1 tapes no problem. but
it is not recommended to write with an LTO3 drive on an LTO2 tape. The
densities do make a difference in operation.
 
Some manufacturers also do not officially support it, but either way,
technically you should be able to read/write LTO2 tape with an LTO3
drive, but you'll be limited to the normal LTO2 capacity.

Subject: [Veritas-bu] LTO3 Read/Write LTO2


Well,  My boss just got me a new LTO3 drive to put in my library.  I
asked for an LTO2 as I already have 2 of these in the lib and 100's of
tapes but I have one nonetheless
The lib sees the drive as does NetBackup but it says that there are no
tapes available...barcode reader I'm sure.  
Is there a way to make the LTO3 use the LTO2 tapes and write to them at
the proper density ?
I tried changing the type to hcart2 as my others are but it did not
take.  I may have to restart services but have to wait for some jobs to
finish.  Figured I'd throw it up to the group while I wait.
