Is this supposed to work? I have no idea; I do know that it was
possible to use DECnet over CI under OpenVMS, but I don't recall
ever seeing that as a possibility for the VMS IP stack. Is
Ultrix supposed to be able to do this? Right now the details elude me. However, it might be
worth
trying just the two VAXen in the cluster to start with (i.e. pull
out the StingRay and the HSC95) and see if the VAXen can see each
other at all. Naturally, I'd boot OpenVMS and cluster them to
prove it works, but I suspect you'd prefer a different approach :-)
Obviously, if your only attached drives are connected over the CI,
then you may have to think of something else!
Minimizing the configuration is always a good start. I'd start with one
VAX, and the HSC95. The HSC can give some diagnostics and information of
the CI which can be useful.
One suggestion is to make sure that all nodes have different addresses,
and that all are under 16, unless they all are configured for a 32-node
CI.
Other obvious things are to make sure the cables really are connected
correctly. TX to TX and RX to RX, channel A and B separate, and so on.
Also, while Gunther don't mention it, I hope (and assume) that there is a
star coupler in the middle.
