CI trouble

Hi, I have hooked up 2 VAX6k and 1 HSC90 and one MTI StingRay CI-SCSI adapter to my two star couplers all properly. Still I could never get any of my CI stuff to work. I tried under ULTRIX 4.5 just to ping through the SCS (?) IP physical/data-link layer but to no avail. Don't get any errors configuring the interface and pinging, just no host reachable. I may not have the CI nodes configured right, I may need to figure out how to plug the jumpers on the VAXBI backplane. Two additional observations: my HSC90 reports K.ci status 111 and the CI LINK module tells me it is not happy. Also, when I try to boot any of the VAXen from media that I don't think is really bootable, I get some funny error on the console: "Insufficient memory for CI" (even though I have full boat of memory 0.5 GB in each VAX.) Could everyone be unhappy about something strange in the CI system? Otherwise: - who knows how the CIBCA is configured with the jumpers? - who knows how best to debug CIBCA under Ultrix or VMS? - who knows how to set up (and debug!) IP over CI on Ultrix? (I do not dare ask about IP over CI on VMS, but appreciate if there are answers.) I also have a VAX6000 Diagnostics tape (TK50) which I should be using. I tried booting from it but I get this "insufficient memory for CI" error soon after the first few blocks are read from tape. I also didn't see much in the way of VMB.EXE on that tape. Anyone know what to do with a VAX6k diagnostics tape? Do I need to use it under VMS? (PS: if someone needs VAX6k diagnostics, I could help :-) regards, -Gunther
