Inthisconfiguration,thereisonefaultdomainbecausethereisasingleFCfabric.Each

Prerequisites
 EachcontrollermusthavetwoavailableFCfront‐endports.
 Therequirementsforvirtualportmodemustbemet.
Steps
1 ConnecteachservertotheFCfabric.
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
