To Create an FCoE Port

Before You Begin

Before you begin this procedure, you must perform the following tasks:

• Enable the 802.3x (also called PAUSE) setting on the Ethernet interface. This setting ensures a lossless Ethernet transport.

• Enable jumbo frames (greater than 2.5 Kbytes) on the Ethernet interface. A Fibre Channel data frame can be as large as 2136 bytes.

These settings can vary for different Ethernet hardware and drivers. In most cases, you must modify the driver.conf file of the Ethernet interface and then reboot. See the driver.conf file for your Ethernet interface for details on how to enable these features.

Each virtual port must have a port and node name. The port name must be unique on the SAN. You can assign names manually or use the built-in WWN generator. If you attempt to register duplicate names, the switch will report an error status on the newly registered WWN, and the switch will not register the new WWN. For more information on acceptable name formats, refer to the T11 standard: Fibre Channel Framing and Signaling (FC-FS 2).

If you try to create an FCoE port on a network interface that does not support FCoE (for example, xnf in xVM or VNET in LDom), an error occurs and the FCoE port is not created.

1. Become superuser.

2. Create an FCoE port.

   # fcadm create-fcoe-port -p Port_WWN -n Node_WWN Ethernet_Interface

   If the selected Ethernet interface does not support Multiple Unicast Address, you are prompted to explicitly enable promiscuous mode on that interface.

   # fcadm create-fcoe-port -f Ethernet_Interface

Example 7–1 Creating an FCoE Port

The following example creates an FCoE port on Ethernet interface nxge0 with port WWN and node WWN generated automatically.

# fcadm create-fcoe-port nxge0
