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 but 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-chained enclosure. And, you
can connect up to four MD1200 and MD1220 to a PERC H800 and PERC
H810 controller in a daisy-chained enclosure. For an example of a daisy chain
configuration (for PERC 6/E controller.), see Figure 7-1.
