Chapter X. FCoE PDU Offload Target

2. Software/Driver Loading

FCoE PDU Offload Target driver (chfcoe) is dependent on Network (cxgb4) and SCST (scst)
drivers. SCST driver will be installed by default during Unified Wire Installation.
Any existing version of SCST driver will be replaced by version 3.0.0-pre2
Important
during installation.
The driver must be loaded by the root user. Any attempt to load the driver as a regular user will
fail. It is recommended that MTU of minimum 2180 is set on all the Chelsio interfaces on which
you are planning to run FCoE PDU Offload Target.
If older versions of cxgb4 and scst drivers are loaded, please unload them
Note
before proceeding.
To load the driver in FCF mode, run the following command:
[root@host]# modprobe chfcoe
To load the driver in VN2VN mode, run the following command:
[root@host]# modprobe chfcoe chfcoe_fip_mode=1
To load the driver in VN2VN mode with VLAN support, run the following command:
[root@host]# modprobe chfcoe chfcoe_fip_mode=1 chfcoe_vlanid=<vlan_id>
Alternatively, you can edit /etc/modprobe.d/chfcoe.conf for specifying VN2VN and VLAN
options.
