Possible solutions
Replace the failed drive. See
Chapter 5, "Replacing
components," on page 93 for
more information.
Verify the drive and part number
to make sure that it is supported
by the DS3500. See
http://www.ibm.com/systems/
storage/disk/.
Replace the RAID controller. See
Chapter 5, "Replacing
components," on page 93 for
more information.
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.
Use the DS Storage Manager
software to confirm the failure;
then, replace the failed battery
unit.
Replace the SAS cable.
Check the SAS host bus adapter
in the host and replace the
adapter if necessary.
Replace the controller. See
Chapter 5, "Replacing
components," on page 93 for
more information.
A fault LED is lit somewhere on
the storage subsystem (check for
amber LEDs on components).
Open the Subsystem
Management window and click
Recovery Guru to see problems
in the DS3500 configuration.
Some errors cause the system
error LED to be lit but 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.
