Message Description Recommended Action
System board is
unable to identify
which slots the
controllers are in
Slot indicator on motherboard is not
working correctly. It appears to the
firmware that both controllers are in
the same slot.
Make sure that controllers are fully seated.
If the problem persists, this might indicate a
controller problem or a system board problem.
Follow these steps:
1. Remove one of the controllers in the
configuration and see if the remaining
controller generates a POST message.
2. Move the remaining controller to the other
slot and see if it still generates a POST
message.
3. Repeat steps 1 and 2 for other controller.
If both controllers give POST messages in one
slot but not the other, it is a system board
problem.
If only one controller has a POST message,
replace that controller.
This controller
cannot see the
drives but the
other controller
can
The other controller in the redundant
controller configuration cannot see
the drives, but this controller can.
Resolve any other errors and then rerun ADU.
