In a daisy chain scenario where more than one enclosure is connected to a controller in a redundant path mode, Storage Management allows you to connect a
maximum of three enclosures in a daisy chain. See the figure below for an example of a daisy chain configuration.
If the communication channel between the connector and the first enclosure is lost, the redundant path configuration itself is lost. In this case, the health of
the logical connector is displayed as critical. Navigate to the Information/Configuration subtab of the logical connector to view details of the "Path Health."
See the table below for a brief outline of this scenario.
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. See the table below for a brief outline of this scenario.
In this case, the enclosure status is displayed in warning mode. The Enclosures page displays all enclosure components (EMMs, Fans, Physical Disks, Power
Supplies, and Temperature) to be in normal condition. Select the Information/Configuration subtab of the enclosure. This page displays the Path Failure
message to indicate that the enclosure has lost a communication path to the controller, thereby indicating that the enclosure is no longer in redundant path
mode. For more information, see "Path Health."
