So you are asking "Can a LTO2 drive read a LTO2 cartridge written in
LTO2 format"?

The answer is it should work! (Perhaps if these are different vendor
drives there could be problems?)

We have something similar working - we have 3 LTO1 drives and 1 LTO2
drive in the same library using all LTO1 media.  The LTO2 drive is
writing in LTO1 format.  The LTO1 drives are able to read (and write)
tapes written in LTO1 format from the LTO2 drive.

Hi,
Yes it's possible to write on cartridge one generation back, and to read
two generations but it's not exactly my question.

I found this redbook, very interesting and accurate but not my answer
The IBM TotalStorage Tape Libraries Guide for Open Systems SG24-5946-02

Is it possible (which constraints) to read (maybe write) with LTO2
drives,
LTO2 cartridges written with LTO3 drives (using LTO2 format?) ? 

Thanks

My understanding is on LTO, that they should be able to read and write
down one level of LTO.  This will usually entail a performance hit too,
but at least it should work.  

As far as documentation... Sorry, I don't remember where I go it.
