causinganoutage.
Inthisconfiguration,fourfaultdomainsarespreadacrossbothcontrollers.Eachfault
domaincontainssetsofprimaryandreservepaths(P1‐R1,P2‐R2,P3‐R3,andP4‐R4).To
provide
redundancy,theprimaryportandthecorrespondingreserveportinafault
domainmustconnecttothesamefabric.WhenMPIOisconfiguredontheFCservers,the
primarypathsprovideredundancyforasingleportorcablefailure.Thereservedpaths

Prerequisites
EachcontrollermusthavetwoavailableFCfront‐endportsforeachFCfabric.
Steps
1 ConnecteachFCservertobothFCfabrics.
2 Connectfaultdomain1(showninorange)tofabric1.
 PrimaryportP1:ControllerA,slot1,port1→Fabric1
 ReservedportR1:ControllerB,slot1,port1→Fabric1
3 Connectfaultdomain2(showninblue)tofabric1.
 PrimaryportP2:ControllerB,slot2,port1→Fabric1
 ReservedportR2:ControllerA,slot2,port1→Fabric1
4 Connectfaultdomain3(showningreen)tofabric2.
 PrimaryportP3:ControllerA,slot1,port2→Fabric2
 ReservedportR3:ControllerB,slot1,port2→Fabric2
5 Connectfaultdomain4(showninpurple)tofabric2.
 PrimaryportP4:ControllerB,slot2,port2→Fabric2
 ReservedportR4:ControllerA,slot2,port2→Fabric2
6 ConfigureFCzoningtomeetthelegacymodezoningrequirements.
