On the ESXi host, bind an iSCSI or iSER adapter with a VMkernel adapter.

The following types of adapters require the port binding:
  • Software iSCSI adapter
  • Dependent hardware iSCSI adapter
  • VMware iSCSI over RDMA (iSER) adapter


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.

Required privilege: Host.Configuration.Storage Partition Configuration


  1. In the vSphere Client, navigate to the ESXi host.
  2. Click the Configure tab.
  3. Under Storage, click Storage Adapters, and select the appropriate iSCSI or iSER adapter (vmhba# ) from the list.
  4. Click the Network Port Binding tab and click the Add icon.
  5. Select a VMkernel adapter to bind with the iSCSI or iSER adapter.
    Note: Make sure that the network policy for the VMkernel adapter is compliant with the binding requirements.
    You can bind the software iSCSI adapter to one or more VMkernel adapters. For a dependent hardware iSCSI adapter or the iSER adapter, only one VMkernel adapter associated with the correct physical NIC is available.
  6. Click OK.
    The network connection appears on the list of network port bindings for the iSCSI or iSER adapter.

    The screenshot shows the Network Port Binding panel. The panel lists the VMkernel adapter vmk1 connected to the iSER adapter vmhba66.
