If the communication channel between the connector and the first enclosure is lost, the redundant path configuration is lost. In
this case, the health of the logical connector is displayed as critical. Navigate to the Information/Configuration page of the
logical connector to view details of the Path Health. For a brief outline of this scenario, see the following table:

However, if the communication channel between any two enclosures is lost, the redundant path configuration is degraded and
the health of the logical connector is displayed as degraded. For a brief outline of this scenario, see the following table.

In the above scenario, the enclosure status is displayed as Warning. Clicking Information/Configuration in the Enclosures
page displays all enclosure components (EMMs, Fans, Physical Disks, Power Supplies, and Temperature) in normal condition.
The Path Failure message indicates that the enclosure has lost a communication path to the controller and the enclosure is no
longer in redundant path mode.
