reading from LTO2 tapes with PowerBlade AS/400

We are soon getting a new AS/400 machine 8406-70Y to be installed in our Bladecenter-H. The machine will be connected via Fibre Channel to a new TS3100 Tape Storage device which contains a LTO5 drive. However we need to read old LTO2 tapes in the future - maybe even years from now. In case we'd keep the old machine alive, we would have no problem reading the old tapes with the external LTO3 SCSI drive, however we do not want to keep this machine forever. Is it maybe possible to connect the old external tape drive to one of our Windows (2008R2) machines and publish the drive via iSCSI, can this be used from AS/400 machines for reading the old tapes ?

If you added a LTO-4 drive to your library it would allow you to read the LTO-2 media, the drive is supported and so is its ability to read lto-2 media, not sure if lto-2 media supported in the ts3100 though.

Do you have a lot of these tapes?

yes the tapes are AS/400 save tapes. My idea would be to mount the old external SCSI drive to a Windows computer using StarWinds iSCSI target software and use this from the AS/400 using iSCSI. I have not done this yet and I'm wondering if this would work. I've also seen that there are external SCSI-iSCSI bridge boxes available for $700. But the question would be the same: could this be used from the new machines with iOS V7R1 ?
connollyg, yes adding a LTO4 tape to the TS3100 would work but this is rather expensive (in fact much more expensive than the LTO5 drive) and we decided against this. Yes, we have a LOT of these tapes and we can not take the time to convert them in advance, we just occasionally want to read from them.

What I'm after is if it is maybe possible to mount the external tape via iSCSI. I could then purchase a iSCSI bridge box or publish the tape via StarWinds iSCSI target software.
DupTap the tapes to a virtual tape drive on the existing 400, then FTP the image & virtual tape drive to a box  (old pc w/a 4 1TB hd's  mirrored and Linux works good - I like Suse), where you can store it. If you need it later you can ftp to the new 400 and mount the virtual tape. You could also just do this to the new box and dup the tapes to LTO5 media also. You can create multiple virtual tape images and even if you have a ton of tapes, this isn't that big of a deal with a little CL and some time.

Of course if you are duping this all to new LTO5 tapes, have a lot of tapes to dup, then it might be cheaper to put in the LTO4 drive.
