c Make sure that you are using the existing switch, and click Next.
d Click the Add adapters icon, and select one or more network adapters (vmnic#) to use for iSCSI.
With dependent hardware iSCSI adapters, select only those NICs that have a corresponding iSCSI
component.
e Complete conguration, and click Finish.
5 Create iSCSI VMkernel adapters for all physical network adapters that you added.
The number of VMkernel interfaces must correspond to the number of physical network adapters on
the vSphere standard switch.
a Click the Add host networking icon.
b Select VMkernel Network Adapter, and click Next.
c Make sure that you are using the existing switch, and click Next.
d Complete conguration, and click Finish.
What to do next
Change the network policy for all VMkernel adapters, so that only one physical network adapter is active
for each VMkernel adapter. You can then bind the iSCSI VMkernel adapters to the software iSCSI or
dependent hardware iSCSI adapters.
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 trac. 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 Seings 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.
