How to implement FCoE interface on OL 6.3

Hi everybody,

 

I try to enable FCoE on a server with Oracle Linux 6.3 but I have some troubles...

 

The server is an UCS C240-M3 with an UCS 1225 VIC (Virtual Interface Card). Per default, my Linux has set 6 network interfaces with DHCP (eth0 -> eth5). It corresponds to a 4 Gigabit PCI card + 2 Virtual NIC from the VIC 1225 adapter. The VIC 1225 is supposed to be used for Networking and FCoE, thanks to VLANs.

 

Linux displays two FCoE devices with lspci:

 

[root@localhost /]# lspci | grep -i fcoe
0d:00.0 Fibre Channel: Cisco Systems Inc VIC FCoE HBA (rev a2)
0e:00.0 Fibre Channel: Cisco Systems Inc VIC FCoE HBA (rev a2)

 

And it appears that drivers are well installed:

 

[root@localhost ~]$ dmesg | grep fnic
fnic: Cisco FCoE HBA Driver, ver 1.5.0.1
fnic 0000:0d:00.0: PCI INT A -> GSI 46 (level, low) -> IRQ 46
fnic 0000:0d:00.0: setting latency timer to 64
fnic 0000:0d:00.0: irq 75 for MSI/MSI-X
fnic 0000:0d:00.0: irq 76 for MSI/MSI-X
fnic 0000:0d:00.0: irq 77 for MSI/MSI-X
fnic 0000:0d:00.0: irq 78 for MSI/MSI-X
scsi1 : fnic
fnic 0000:0e:00.0: PCI INT A -> GSI 40 (level, low) -> IRQ 40
fnic 0000:0e:00.0: setting latency timer to 64
fnic 0000:0e:00.0: irq 79 for MSI/MSI-X
fnic 0000:0e:00.0: irq 80 for MSI/MSI-X
fnic 0000:0e:00.0: irq 81 for MSI/MSI-X
fnic 0000:0e:00.0: irq 82 for MSI/MSI-X
scsi2 : fnic

 

How can I enable FCoE on my Linux ? I found some help on the Internet, and examples show how to use ethN interface etc.... I don't know how we habitually identify the interface (eth*) to use with FCoE. Is the FCoE interface considered as a "network" interface by Linux, and generates a script in /etc/sysconfig/network-script ? Am I supposed to see additional interfaces (eth6 and eth7) and use it for FCoE ?

 

Thanks
