Setting The Redundant Path Configuration
Does my Controller Support This Feature? See Supported Features.
Redundant path is supported only on external PERC cards that use firmware version 6.1 and later. A
redundant path internal to the system is not supported. MD1xxx enclosures are supported.
For redundant paths, the enclosure must be in the Unified mode however specific port connections are
not required. A connection from either controller ports to either EMM In ports creates the redundant path
as long as two cables are used. But, Redundant Path continues to appear in the field even as the
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. You can connect up to four MD1400 and MD1420 to a PERC H830 controller
and SAS 12 Gbps adapter 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
