If it's a single drive LTO2 that appears to be working itself (that is you can load a tape and unload a tape and it shoes no errors) then:

Check all the cables.
Check the terminator.

If all are good open the top cover of the thing and check to be sure the internal SCSI cable hasn't pulled free from the back of the actual drive. It might appear connected but assure that it's fully seated. That cable goes from one of the two SCSI connectors on the back of the case to the drive and then to the other case connector. Don't ask me how I know this can be a problem.......

Thanks, Nathan.

I am only in need of a single tape device. A tape library would be fine as well (it would save me the trouble of loading tapes every day).

I do have a single tape LTO-2 tape drive, but I need to do a bit of investigation on it. It's hooked into my dev box, but it's not being detected (even when I IPLed the box). So I'm not sure if the tape drive is bad or if there's a misconfiguration somewhere.

It looks like your server has only 6 disk drives of 35 GB each. If they happen to be mirrored, then it appears your backup would fit on a pair of
70 GB tapes. Do you really need a tape library? Or would a single tape drive suffice?

Geez, I'm a goof....Monday morning fog.

Here's the rack config....and this will be our development box for the
immediate future (and probably for at least three years or more). Box
is currently running 6.1 and will probably move to 7.1 soon (for testing).
