There was an error in communication between the physical drive and the controller while the controller was attempting to validate the RAID configuration of the physical drive.
If you cannot identify a connection problem, the replacement order for parts is the following:
Before replacing a physical drive or controller, verify that it is updated
with the latest firmware (microcode) and that they still fail.
Note: If multiple
physical drives are marked defunct within the same time period, check the cables
and backplanes.
