pNIC virtual mode

(IBM Flex System devices only) The following topic provides information about the pNIC virtual mode.

About this task

In pNIC virtual mode the IBM Flex System CN4022 2-Port Adapter shows the physical characteristics of the adapter through the uEFI utility. The adapter contains two physical ports with the Ethernet, iSCSI offload and FCoE offload personalities automatically enabled. Each port has one MAC (Ethernet) address, one MAC (iSCSI) address, and one WWN (Fibre Channel) address. The MAC addresses have factory default values that can be changed.


To configure the IBM Flex System CN4022 2-Port Adapter for use in IFM using the pNIC virtualization mode, complete the following steps:
  1. From the uEFI utility, select System Settings > Network and select the port to configure.
  2. Select the pNIC virtualization mode from the Main Configuration Page.

    The Permanent MAC Address is the same for each port. After IFM is applied, the Virtual MAC Address is different for each port and is used by the adapter and the device drivers in the OS.

  3. Use the information in Profiles to apply an IFM pattern to the IBM Flex System CN4022 2-Port Adapter.

What to do next

Optionally, you can verify the configuration of the adapter through the uEFI utility, IFM, and the CMM CLI mode.

  1. Verify that the adapter uses the new addresses from the IFM configuration. The compute node has a new virtual MAC address on the Main Configuration Page.
  2. Verify that IFM reflects the address consumption. The adapter is inserted in Mezz 2, and has 2 ports. Both Port 1 and Port 2 have Normal status, which means the ports consumed the new addresses.
  3. To verify Fibre Channel consumption from the uEFI utility, go to the Main Configuration Page for the port. To verify Fibre Channel consumption through IFM, see Hardware devices.
  4. You can verify the address consumption through the CMM CLI mode.
