Virtual Port Mode with Dual-Fabric Fibre Channel
UsetwofabricswithvirtualportmodetopreventaFCswitchfailureorcontrollerfailure
fromcausinganoutage.
Inthisconfiguration,thereisonefaultdomainforeachFCfabric.Eachcontrolleris
connectedtobothfabricsbytwoFCconnections.Ifasingleportfails,itsvirtualport
fails
overtoanotherportinthesamefaultdomain.Ifacontrollerfails,thevirtualportsonthe
failedcontrollermovetoportsontheothercontrollerinthesa mefaultdomain.
Prerequisites
 EachcontrollermusthavetwoavailableFCfront‐endportsforeachFCfabric.
 Therequirementsforvirtualportmodemustbemet.
Steps
1 ConnecteachservertobothFCfabrics.
2 Connectfaultdomain1(showninorange)tofabric1.
 ControllerA,slot1,port1→Fabric1
 ControllerA,slot2,port1→Fabric1
 ControllerB,slot1,port1→Fabric1
 ControllerB,slot2,port1→Fabric1
3 Connectfaultdomain2(showninblue)tofabric2.
 ControllerA,slot1,port2→Fabric2
 ControllerA,slot2,port2→Fabric2
 ControllerB,slot1,port2→Fabric2
 ControllerB,slot2,port2→Fabric2
4 ConfigureFCzoningtomeetthelegacymodezoningrequirements.
