Change Network Policy for iSCSI
If you use a single vSphere standard switch to connect multiple VMkernel adapters to multiple network
adapters, set up network policy so that only one physical network adapter is active for each VMkernel
adapter.
By default, for each VMkernel adapter on the vSphere standard switch, all network adapters appear as
active. You must override this setup, so that each VMkernel adapter maps to only one corresponding active
physical. For example, vmk1 maps to vmnic1, vmk2 maps to vmnic2, and so on.
Prerequisites
Create a vSphere standard switch that connects VMkernel with physical network adapters designated for
iSCSI trac. The number of VMkernel adapters must correspond to the number of physical adapters on the
vSphere standard switch.
Procedure
1 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  icon.
5 On the Edit Seings 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 Adapters
category.
7 Repeat Step 4 through Step 6 for each iSCSI VMkernel interface on the vSphere standard switch.
Example: iSCSI Network Policy
The following table illustrates the proper iSCSI mapping where only one physical network adapter is active
for each VMkernel adapter.
VMkernel Adapter (vmk#) Physical Network Adapter (vmnic#)
vmk1 Active Adapters
vmnic1
Unused Adapters
vmnic2
vmk2 Active Adapters
vmnic2
Unused Adapters
vmnic1
What to do next
After you perform this task, bind the virtual VMkernel adapters to the software iSCSI or dependent
hardware iSCSI adapters.
Bind iSCSI and VMkernel Adapters
Bind an iSCSI adapter with a VMkernel adapter.
Prerequisites
Create a virtual VMkernel adapter for each physical network adapter on your host. If you use multiple
VMkernel adapters, set up the correct network policy.
