This isn't answering your question, but we've had a fair amount of
excitement with A5200s, and there are two issues which have made
things better: make sure the disk firmware is right, and beware of
taking disks out of some slots in the arrays. Wrong disk firmware
seems to be able to cause intermittent total loss of contact with the
array, and removing disks from the wrong slots can cause weirdo loop
flapping problems.
