We had something similar two or three disk slots which started to act
weird and failed quite often - usually starting with a high error rate.
After exchanging two hard drives, the Sun hotline initiated to exchange
the backplane - essentially the chassis was replaced.
Since then, we have not encountered anything like this anymore.
So it *might* be the backplane or a broken Marvell controller, but it's
hard to judge.
