Message Description Recommended Action
System board is
unable to identify
which slots the
controllers are in
Slot indicator on system board is
not working correctly. Firmware
recognizes both controllers as
being installed in the same slot.
1. Make sure both controllers are fully seated
in their slots.
If the problem persists, this might indicate a
controller problem or a system board
problem.
2. Remove one of the controllers in the
configuration and see if the remaining
controller generates a Power-On Self-Test
(POST) message.
3. Move the remaining controller to the other
slot to see if it still generates a POST
message.
4. Repeat these steps with the other
controller.
If both controllers give POST messages in one
slot but not the other, it is a system board
problem. If one of the controllers gives POST
messages and the other controller does not,
replace the controller that is giving the POST
messages. Contact a Compaq authorized service
provider for any warranty replacements.
The redundant
controllers installed
are not the same
model.
SOLUTION: Power
down the system
and verify that the
redundant
controllers are
different models. If
they are different
models, replace the
other controller with
the same model as
this one.
ADU detected two different
controller models installed in a
redundant controller configuration.
This is not supported, and one or
both controllers may not be
operating properly.
Use the same controller models for redundant
controller configurations.
This controller
cannot see the
drives but the other
controller can
The other controller in the
redundant controller configuration
can recognize the drives, but this
controller cannot.
Resolve any other errors and then rerun ADU.
This controller can

Resolve any other errors and then rerun ADU.
