Use the esxcli command to enable the VMware iSER adapter.

Prerequisites

  • Make sure that your iSCSI storage supports the iSER protocol.

  • Install the RDMA-capable adapter on your ESXi host.

  • Use the RDMA-capable switch.

  • Enable flow control on the ESXi host. To enable flow control for the host, use the esxcli system module parameters command. For details, see the VMware knowledge base article at http://kb.vmware.com/kb/1013413.

  • Make sure to configure RDMA switch ports to create lossless connections between the iSER initiator and target.

Procedure

  1. Use the ESXi Shell or vSphere CLI to enable the iSER adapter:

    esxcli rdma iser add

  2. Verify that the VMware iSER adapter has been added:
    1. Navigate to the host.
    2. Click the Configure tab.
    3. Under Storage, click Storage Adapters, and review the list of adapters.

      If you enabled the adapter, the adapter (vmhba#) appears on the list under the VMware iSCSI over RDMA (iSER) Adapter category.
