Mixed drive formats in StorEdge L100
Hi,
We are running a TSM service attached to a Sun L100 tape library.
Our wish is to upgrade the library's tape drives from LTO2 to LTO3.
Our ideal solution would be to upgrade only half (3) of the tape units to LTO3, leaving the remaining drives on LTO2.
Can this be done? TSM can handle the mixed media in the library, so from an application point-of-view this is fine, but can it be support on a hardware level?
thanks in advance

You seem to be asking if the LTO-2 tape media is compatible with the LTO-3 drive type.
the answer is yes.
The problem is attempting to mount LTO-3 media in an LTO-2 drive after LTO-3 compression ratios have been applied. The best thing
to do is to create an LTO-3 media pool, and make it so only the LTO-3 drives can mount tapes from it. Without knowing your TSM,
I can't tell you how to do this, but most products allow something like this.

Thanks for your reply,Apologies for not making my question clear.
The question is whether, with an L100 library you can split the drive types between LTO2 and LTO3, having, say, 3 LTO2 drives and 3 LTO3 drives.
I know that L100's support LTO3, just not whether they support LTO2 and LTO3 at the same time.
