Possible solutions
Use DS Storage Manager client software to verify
the failure and replace the power supply and fan
unit.
If you have placed the controller offline, use the
DS Storage Manager client software to place it
online.
If one controller has been placed offline by the
other controller, contact IBM support. (This is the
case if you use the DS Storage Manager client
software to make repeated attempts to bring an
offline controller online, but the controller keeps
reverting back to an offline state.)
If the RAID controller Needs Attention LED is on
and the Service Action Allowed LED for that RAID
controller is lit, replace the RAID controller.
If the Service Action Allowed LED for the RAID
controller is not lit, perform additional diagnostics
to identify other component failures. Replace the
other failed components before replacing the
RAID controller.
Contact IBM Support.
