Prerequisites
EachcontrollermusthavetwoavailableiSCSIfront‐endports.
Steps
1 ConnecteachiSCSIservertobothEthernetswitches.
2 Connectfaultdomain1(showninorange)toswitch1.
 PrimaryportP1:ControllerA,slot3,port1→Switch1
 ReservedportR1:ControllerB,slot3,port1→Switch1
3 Connectfaultdomain2(showninblue)toswitch1.
 PrimaryportP2:ControllerB,slot4,port2→Switch1
 ReservedportR2:ControllerA,slot4,port2→Switch1
Note: Topreventaportorcablefailurefromblockingaccesstovolumesmappedto
acontroller,connecttwoadditionalfaultdomainssothateachcontrollerhastwo
primarypathstotheiSCSInetwork.
