Solution
• Verify that the controller module is properly seated in the slot and
latched.
• Check the RAIDar event log for power-on initialization events and
diagnostic errors.
• Examine the event log to determine if there is any error event and
take appropriate action.
• Call technical support and send in the log and event files.
• Replace the controller that displayed the fault LED.
In a dual-controller configuration, if a conflict between controllers
exists, only controller module A will boot. For example, if the cache
size is different on the controller modules, controller module B will
not boot.
• Replace the controller module where the error occurred.
• The controller might need to have its firmware upgraded or be
replaced.
• Check the specific error code to determine the corrective action to
take.
• Check the power-and-cooling module and the input voltage.
• Check that the enclosure fans are running.
• Check that the ambient temperature is not too warm. See the
planning guide
for temperature specifications.
• Check for any obstructions to the airflow.
When the problem is fixed, event 47 is logged.
• Contact Technical Support.
• The controller module needs to be replaced.
After the failover to the other controller, Event 72 indicates that
recovery has started or has completed.
The controller needs to be replaced.
The downlevel controller needs to be upgraded.
