Troubleshooting
Event: The drive status LED is red.
Cause: This shows a failed drive. A failed drive may be marked as such
because of power failure or media access problem (such as a bad
sector which fails retry). When a drive in a fault tolerant array is
determined to have failed, the remaining drives in the array are
internally adjusted to a later “generation” status to indicate that
they represent the current version of the array.
Fix:
Upon replacing a failed drive, the new drive will be assigned to the
failed drive’s original location. A rebuild will then begin based on
data from the drives in the array that have the latest “generation.”
This “generation” tracking allows accurate reproduction of current
data from the array drives that may have been written to during the
time that the array was critical.
Event: The drive status LED is orange (amber).
Cause: This shows that the drive is in the process of rebuilding, following
some sort of critical array status in a fault tolerant array. The LED
will return to green status when the rebuild is complete and
successful.
Event: The drive status LED does not light up, even though others
light up.
Cause: The keylock on the housing is not turned ON
Fix:
Lock the keylock to transmit power to the drive.
Cause: The drive carrier is not fully and correctly inserted into the drive
housing.
Fix:
Make sure the handle is fully down and the carrier is pushed all
the way into the housing.
Cause: Either the cabling from the controller card to the housing is not
correctly installed or the cabling from the carrier to the drive is not
correctly installed.
