I suspect that it's you config that may be wrong. Each uda can support 4 devices, and you have to (or should) tell config about them. So, your config should look like this: controller uda0 at uba0 csr 0172150 vector udintr disk ra0 at uda0 drive 0 disk ra1 at uda0 drive 1 disk ra2 at uda0 drive 2 disk ra3 at uda0 drive 3 controller uda1 at uba0 csr 0172550(or 0160334) vector udintr disk ra4 at uda1 drive 0 disk ra5 at uda1 drive 1 disk ra6 at uda1 drive 2 disk ra7 at uda1 drive 3 In your configuration, you're asking unix to find ra2 on uda1 drive 2. This is not logically possible. uda0 supports ra0, 1 ,2 and 3, and the next uda device will support ra4, 5, 6 and 7. That is what works for me. Also, logical drive ra4 must be at physical drive 0 on the 2nd uda(not 2). Now I'll admit I don't have this up on a 785, but it does work for the 3 MicarVaxes I run. And I also use the secondary uda address of 0160334 in the MVaxes floating address space. You may want to check on the uda secondary address on a 785, but I don't know why it'd be different. I suggest you try the above configuration. You can even call me if you get stuck, I have done this so many times I think I could do it in my sleep.
