It would appear that I have replicated the problem again... but I have relagated my serial consoles to other more desparate uses. I will go down and check, but from memory, that is typical of the sequence I see. My drives (just to respond to an earlier question) are correctly terminated with manufacturer's parts --- so the LVD chain is terminated with LVD parts supplied by the LVD enclosure maker. The Ultra chain is terminated by an older drive that supports termination ... and there are only two drives on that chain. I think my short-term solution will be to put a second 2940 in the machine so that the root drive will still be functional when this happens.
