Controller Health
This screen displays the status of the controller and the components attached
to the controller.
Controller Severity
Component status is indicated by the severity. A component with a Warning
or Critical/Failure status requires immediate attention to avoid data loss if
possible. A component’s status may indicate the combined status of the
component and its lower-level objects. See Determining the Health Status for
Storage Components for more information.
It may be useful to review the Alert Log for events indicating why a
component has a Warning or Critical status. For additional troubleshooting
information, see Troubleshooting.
