11. Three disks have failed. What should I do?
Swap the single functioning disks with each of the failed disks in turn. If the
functioning disk continues to function at its new location, the original disk was
faulty and should be replaced. If the functioning disk does not function at any of
the three other locations, the drive carriers for those location or the subsystem is
faulty. Perform the next step.
Swap the functioning drive carrier in the same way to find out if the drive carriers
or the subsystem. Replace any malfunctioning drive carriers.
Consult your dealer if the subsystem appears to be faulty.
12. Four disks have failed. What should I do?
If four disks have failed, you will need to use another disk that you know is functioning.
Use this disk in the same way as outlined in the previous answer to find out if the
malfunction is with the original disks, the drive carriers or the subsystem.
