You must connect the VMkernel, which runs services for iSCSI storage, to a physical network adapter.
- Log in to the vSphere Client, and select a host from the inventory panel.
- Click the Configuration tab and click Networking.
- In the vSphere Standard Switch view, click Add Networking.
- Select VMkernel and click Next.
- Select Create a vSphere standard switch to create a new standard switch.
- Select a NIC to use for iSCSI traffic.
If you are creating a VMkernel interface for the dependent hardware iSCSI adapter, select the NIC that corresponds to the iSCSI component. See Determine Association Between iSCSI and Network Adapters.
- Click Next.
- Enter a network label.
A network label is a friendly name that identifies the VMkernel adapter that you are creating, for example, iSCSI.
- Click Next.
- Specify the IP settings and click Next.
- Review the information and click Finish.
You created the virtual VMkernel adapter for a physical network adapter on your host.
What to do next
If your host has one physical network adapter for iSCSI traffic, you must bind the virtual adapter that you created to the iSCSI adapter.
If you have multiple network adapters, create additional VMkernel adapters and then perform iSCSI binding. The number of virtual adapters must correspond to the number of physical adapters on the host.
