Solution
Verify that the Fibre Channel data
cables are properly connected and
there is a valid Link LED illuminated.
Verify that the Fibre Channel data
cable is a known good cable. Replace
the Fibre Channel data cable.
Verify that all the disk drives are
functioning properly.
Verify that the Host I/O Card or Disk
I/O Card is functioning properly. Refer
to "Common Fibre Loop/Bus
Problems" on page 125.
Verify that the Fibre Channel HBA is
functioning properly.
Replace the failed drive component of
the logical array. After the rebuild is
complete the LED should return to
steady green.
Replace the RAID Controller.
Verify that the RAID Controller was not
"stopped" through the software
interface.
Replace the suspect faulty power
supply.
Ensure that all the power supply
switches are in their "On" position.
Replace the missing power supply and
turn it on.
Verify that proper AC power is
available to the power supplies. If the
enclosure is plugged into a three-hole
grounded outlet, verify if power to the
outlet has been interrupted. This can
be accomplished by testing the outlet
with a known working appliance, like
a lamp.
Verify that proper DC power is
available to the power supplies. Test
the DC power feed system.
