redundant path is removed. The redundant path ceases to appear only when it is cleared in the storage

management.

In a daisy-chain scenario, more than one enclosure can be connected to a controller in a redundant path

mode. You can connect up to three MD1000 and MD1120 to a PERC 6/E controller in a daisy-chain

enclosure. You can connect up to four MD1200 and MD1220 to a PERC H800 and PERC H810 controller

in a daisy-chain enclosure. For an example of a daisy-chain configuration (for PERC 6/E controller), see

the following image:

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:

Table 18. Path between Controller and Enclosure 1

Health of Logical Connector Path between Controller and Enclosure 1

Connector 0 (C0) Connector 1 (C1)

Available Available

Available Disconnected

Disconnected Available

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.
