Hm, sure? I would expect the same behaviour (detaching) as with the first
drive if the controller was the reason in this case.

I already thought about replacing the controller to get rid of the
detach-problem. However, I cannot do this online and I really would prefer
fixing the disk firmware problem first.
I could remove the hotspare drive ad14 and use this slot for putting in a
replacement disk. Is it possible to get ad18 out of zfs' replacing
process? Maybe by detaching the disk from the pool?
