Fernando,

The format written to LTO cartridges depends on the medium type. So if you
use an LTO1 cartridge with an LTO2 drive, the format should be LTO1 format.
And an LTO1 drive should be able to read data from the LTO1 cartridge.To be
sure, you can also set format in devclass to "ultriumc".

Hunny Kershaw

Hello,

We are using an STK L180 with 6 LTO (SEAGATE) drives and running TSM 5.1.6.
Now we want to add 2 LTO2 drives, and we are evaluating the using LTO2.

The question is...
Can we use LTO2 drives as LTO1 drives? I.e, write LTO1 tape format in LTO2
drive and in the same device class?
If yes, can LTO1 read the tape used by LTO2 drive?

Finally, we intend to add LTO2 drives but use the same capacity (LTO1).
Can TSM driver manage this or is an hardware compatibility issue?



TIA,
