Problem
indicator
Component Possible cause Possible solutions
Amber LED is lit Drive (drive
fault LED) Drive failure Replace the failed drive.
Drive uncertified Verify the drive and part number
to make sure that it is supported
by the DS3300. (See
http://www.ibm.com/systems/
storage/disk/ds3000/ds3300/.)
RAID controller
(service action
required LED) RAID controller
failure Replace the RAID controller. See
Chapter 5, “Replacing
components,” on page 63 for
more information.
The controller was
placed offline by a
user or the other
controller. Use the Subsystem Management
window to place the controller
back online. If the controller
continues going to an offline state
after being placed online, replace
the RAID controller.
RAID controller
(battery fault
LED) Battery unit failure Use the DS3000 Storage
Manager software to confirm the
failure; then, replace the failed
battery unit.
RAID controller
(SAS link
service action
LED) SAS cable failure Replace the SAS cable.
SAS host bus
adapter failure Check the SAS host bus adapter
in the host and replace the
adapter if necessary.
SAS port failure Replace the controller.
Front bezel
(system error
LED)
General machine
fault A fault LED is lit somewhere on
the storage subsystem (check for
amber LEDs on components).
General machine
fault (continued) Open the DS3000 Storage
Manager Subsystem
Management window and click
Recovery Guru to see problems
in the DS3300 configuration.
Some errors will cause the
system error LED to be lit but will
not cause any individual
component fault LEDs to be lit.
(Drive PFA exceeded or nominal
temperature exceeded errors are
examples.) Follow the corrective
actions in the Recovery Guru
window.
Amber LED is lit
and green LED is
off Power supply
(fault and
power LEDs
are lit)
The power switch is
turned off or there is
an ac power failure. Replace the failed power supply
or turn on all power-supply
switches.
