Disconnect the B-side Chain
DisconnecttheenclosuretoberemovedfromtheB‐sidechain.
1 DisconnecttheB‐sidecablefromControllerA:slot3,port3.TheAsidecontinuesto
carryIOwhiletheBsideisdisconnected(seeFigure 126onpage 197).
2 IntheStorageCenterSystemManager,selectStorageManagement→System→
Setup→ConfigureLocalPorts.
3 Makesurethat:
 SlotandslotportsareUpandthePurposeissettoback‐end.
 TargetCountequalsthenumberofaddeddrives,demonstratingthatthecontroller
recognizesthenewenclosures.
4 RemovethecablebetweenEnclosure1:right,portA→Enclosure 2:right, portB(see
Figure 126onpage 197).
5 MovethecablefromEnclosure2:right,portC→Enclosure1:right,port B(see
Figure 126
onpage 197).
6 ReconnecttheB‐sidecabletoControllerA:slot3,port3(seeFigure 127onpage 198).
7 Theenclosureisnowdisconnectedandcanberemoved.

Caution: TodisconnecttheB‐sidecablingwithoutasystemoutage,makesurethat
youfirstdisconnecttheB‐sidecablefromthecontroller.Disconnectinganyother
cablefirstdisruptsIOtotheenclosure,resultinginasystemoutage.
