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.
