Hi.
1. Gen 2 will be able to write on the Gen1 Cartridges (I done it with
LTO 3582 )
2. according to IBM spec sheets Gen1 is 15-30 MB/s, but with LTO2
Drives its 20-40 MB/s writing on LTO2 cartridges.
3. I not sure if LTO1 drive can write on LTO2 cartridge, but if it
can, u can change the format to drive instead of LTO in the Device
Class.
I hope it answer your questions.

Subject: Gen1 to Gen2 Upgrade/coexist
Am using an LTO 3583 with 2 scsi Gen1 drives and GEN1 cartridges.
Planning
to upgrade to 4 fiber Gen2 drives in the 3583. The SCSI drives will be
removed. The current data exists on over 150 gen1 cartridges and hence
do
not plan to move to gen2 cartridges immediately. The setup is directly
attached to the pSeries servers running AIX 5.1 and TSM Server
Got some queries
1. Will Gen2 drives be able to read and write(new as well as append to
existing tapes) on the existing gen1 cartridges without problem?
2. What speed will I get out of the new setup? Gen2 speed or Gen1 speed?
3. If I coexist the new gen2 drives with the existing gen1 drives where
can
I get stuck?
Anyone experienced in this kind of a scenario?
Anoop
