Fibre Channel Zoning
WhenusingFibreChannelforfront‐endconnectivity,zonesmustbeestablishedtoensure
thatstorageisvisibletotheservers.Planthefrontend connectivityusingzoningconcepts
discussedinthissectionbeforestartingtocablethecontroller.
Zoningcanbeappliedtoeithertheportsonswitchesorto
theWorldWideNames(WWNs)
oftheenddevices.Zonesshouldbecreatedusingasingleinitiator(usingphysicalWWNs)
andmultipletargets(usingvirtualWWNs).
Inadual‐controllerconfiguration,thevirtualWWNsfromeachcontrollermustbe
includedinthezonewitheachhost’sWWN.
WWN Zoning Guidelines
WhenWWNzoningisconfigured,adevicemayresideonanyportorchangephysical
portsandstillbevisiblebecausetheswitchisseekingaWWN.
Port Zoning Guidelines
Whenportzoningisconfigured,onlyspecificswitchportsarevisible.Ifastoragedeviceis
movedtoadifferentportthatisnotpartofthezone,itisnolongervisibletotheotherports
inthezone.
Note: Forvirtualportmode,WWNzoningisrecommended.
Connectivity Type Guidelines
Legacymode • IncludeallStorageCenterfront‐endWWNsorportsinasingle
zone.
• Createserverzonesthatcontainasingleinitiatorandmultiple
targets,andwhichincludetheserverHBAWWN.
Virtualportmode • IncludeallStorageCentervirtualWWNsinasinglezone.
•IncludeallStorageCenterphysicalWWNsina

serverHBAWWN.
FibreChannelreplication • IncludeallStorageCenterphysicalWWNsfromSystemAandB
inasinglezone.
•IncludeallStorageCenterphysicalWWNsofSystemAandthe
virtualWWNsofSystemBontheparticularFabric.

Note: Someportsmaynotbeusedordedicatedforreplication,
howeverportsthatareusedmustbeinthesezones.
