Sorry to trouble the list with this one. I had no responses which was
probably what I deserved since it turned out that my problem was, you
guessed it, a
BAD SCSI CABLE
My original question was:
>I'm trying to set up a WangDAT3400DX drive on a Solaris 2 machine.
>The relevant lines I put in my `/kernel/drv/st.conf' file are:
> "WangDAT Model 3400DX ","WangDAT 4mm DAT", "DAT2",
>DAT2 = 1,0x34,0,0xd639,4,0x00,0x8c,0x8c,0x8c,1
>This is my best guess based on my SunOS 4.1.3 setup but I'd appreciate
>anyone letting me know where I can find definitive info. I can't see
>any WangDAT info on the net and our suppliers are unhelpful.
>Anyway, during reboot I get a bunch of messages:
