Hi Amy, I suspect someone has already told you this, so forgive me if this is a repeat. But have you been told that the AIT 2 drive needs to emulate an AIT 1 drive in order to work? In the next major release of software the AIT 2 will be supported, but right the only way it will work is for it to pretend to be an AIT1.
I've seen several messages over the past few months with similar information and I just have one question. Does this mean that I am hallucinating when I watch my F-740 run the backups to my directly attached AIT-2 tape drive? The filer is running OnTap 5.3.4R2. The drive in question is a Sony SDX-500C and when I run "sysconfig -t" it reports the first few devices as AIT-1 and the remaining devices as AIT-2. Or maybe I'm hallucinating about that too.

This is supposedly the third tape drive from our vendor (but at least the second I'm sure about) and we have tried internal and external termination (with more than one external terminator). We have sent the drive back to the vendor multiple times and they have tested it and sent it back with us getting the same results. The current drive was sent to us directly from a NetApp engineer (she got it from our vendor) who tested it successfully on a F760. We don't have another system we could test it on ourselves.
I think you may be getting slightly bad assistance from NetApp although I would assume that they didn't intend it to be bad. You say that you have an F720 but that they tested the tape drive successfully on an F760. In my opinion this is not a valid test. The NetApp support people should have a 720 available to do the testing on and if they don't have one they should get one. It sounds like you've replaced just about everything in your machine at this point so unless it's something really dumb like a bad scsi cable it must be some subtle difference between the 720 and the 760.
Question to NetApp: does the 760 use the same scsi controller as the 760? If not, that is the most likely cause of this problem.
