• Under the Health pane, the State is Degraded.
This status refers to the state of the storage system, not the state of an individual component.
• Under the Health pane, the Details indicate that the drive enclosures and drives connected to
the failed controller node are Degraded.
To see a graphical overview of these degraded components, select the Map view.
• Under the Configuration Summary pane, only one controller node is active in the system
because the failed controller node is offline.
The failed controller node does not appear on the controller node page of the SC interface.
7. Locate the failed and shut down controller node by referring to the LEDs.
Some faults illuminate the blue UID/Service LED, which helps you locate the failed component.
When the UID/Service LED is solid blue and the Status LED is rapidly flashing green, a controller
node is shut down. Depending on the nature of the controller node failure, the Fault LED might be
solid amber.
The Fault LED for the other active controller node in the cluster will be flashing, indicating that one of
the other controller nodes in the cluster is shut down.
8. Verify that all cables are labeled with their location.
