Chapter 11 Configuring iSCSI Adapters and StorageWhat to do nextChange the network policy for all VMkernel adapters, so that only one physical network adapter is activefor each VMkernel adapter. You can then bind the iSCSI VMkernel adapters to the software iSCSI ordependent hardware iSCSI adapters.Change Network Policy for iSCSI in the vSphere Web ClientIf you use a single vSphere standard switch to connect multiple VMkernel adapters to multiple networkadapters, set up network policy so that only one physical network adapter is active for each VMkerneladapter.By default, for each VMkernel adapter on the vSphere standard switch, all network adapters appear asactive. You must override this setup, so that each VMkernel adapter maps to only one corresponding activephysical. For example, vmk1 maps to vmnic1, vmk2 maps to vmnic2, and so on.PrerequisitesCreate a vSphere standard switch that connects VMkernel with physical network adapters designated foriSCSI traffic. The number of VMkernel adapters must correspond to the number of physical adapters on thevSphere standard switch.Procedure1 Browse to the host in the vSphere Web Client navigator.2 Click the Manage tab, and click Networking.3 Click Virtual Switches, and select the vSphere switch that you want to modify from the list.4 On the vSwitch diagram, select the VMkernel adapter and click the Edit Settings icon.5 On the Edit Settings wizard, click Teaming and Failover and click Override under Failover Order.6 Designate only one physical adapter as active and move all remaining adapters to the Unused Adapterscategory.7 Repeat Step 4 through Step 6 for each iSCSI VMkernel interface on the vSphere standard switch.Example: iSCSI Network PolicyThe following table illustrates the proper iSCSI mapping where only one physical network adapter is activefor each VMkernel adapter.VMkernel Adapter (vmk#)vmk1vmk2Physical Network Adapter (vmnic#)Active Adaptersvmnic1Unused Adaptersvmnic2Active Adaptersvmnic2Unused Adaptersvmnic1What to do nextAfter you perform this task, bind the virtual VMkernel adapters to the software iSCSI or dependenthardware iSCSI adapters.VMware, Inc. 87
