RAID5 disk firmware question.
There is a RAID5 array which includes 4 146G disk drives. Two of these devices have failed and also failed over to hot spares. One device is failing and is in "needs maintenance" state. There are no remaining hot spares should this device fail. I do see errors on the failing device. I have a plan to replace the two failing devices to free up the hot spares before approaching the failing device.
