I just tried putting an iti-4280 in a AlphaServer and encountered the
following problem. The controller is configure with 5 disks on the A
bus and 3 disks on the second bus. From SRM I can see all 8 disks, but
when Linux boots it creates 4 disk devices, two from the first bus and
two from the second bus. Does this make any sense? When I put 7 of
the disks on a single iti-4140, all seven are seen and the system boots
just fine. I would appreciate any insights.
Only thing occurs to me is bus termination issues; some drivers are
more sensitive to that.
Does it ALWAYS see ALL of however many disks that are installed on one
of the cables, but not always all that are installed on the other
cable? If so, then suspect the second cable and/or its termination.
Good luck.
