It's not right. You might be able to get away
with the exceptions for
stubs to devices if the wires from the terminator to the device and the
open connector are short enough, but that seems unlikely to me,
especially since I think the maximum stub length for that exception is
something like three inches.
As a general point you should never try to 'get away with things' like
this. This applies IMHO to all areas of hardware -- if you do things like
this they will come back to 'bite' you when you least want problems. I
would put everything right (e.g. not have stubs on a SCSI bus) and then
try to sort out remaining problems, knowing that they're genuine
problems, not caused by misuse of hardware.
