C–VirtualNIC Interface Configuration and Administration<br />
VirtualNIC Interface Configuration and Administration<br />
To start the qlgc_vnic driver and the <strong>QLogic</strong> VNIC interfaces, use the following<br />
command:<br />
/etc/init.d/qlgc_vnic start<br />
To stop the qlgc_vnic driver and bring down the VNIC interfaces, use the following<br />
command:<br />
/etc/init.d/qlgc_vnic stop<br />
To restart the qlgc_vnic driver, use the following command:<br />
/etc/init.d/qlgc_vnic restart<br />
If you have not started the InfiniBand network stack (<strong>QLogic</strong> <strong>OFED+</strong> or OFED),<br />
then running the /etc/init.d/qlgc_vnic start command also starts the<br />
InfiniBand network stack, since the <strong>QLogic</strong> VNIC service requires the InfiniBand<br />
stack.<br />
If you start the InfiniBand network stack separately, then the correct starting order<br />
is:<br />
• Start the InfiniBand stack.<br />
• Start <strong>QLogic</strong> VNIC service.<br />
For example, if you use <strong>QLogic</strong> <strong>OFED+</strong> <strong>Host</strong> <strong>Software</strong>, the correct starting order<br />
is:<br />
/etc/init.d/openibd start<br />
/etc/init.d/qlgc_vnic start<br />
If you want to restart the <strong>QLogic</strong> VNIC interfaces, run the following command:<br />
/etc/init.d/qlgc_vnic restart<br />
You can get information about the <strong>QLogic</strong> VNIC interfaces by using the following<br />
script (as a root user):<br />
ib_qlgc_vnic_info<br />
This information is collected from the<br />
/sys/class/infiniband_qlgc_vnic/interfaces/ directory, where there is a<br />
separate directory corresponding to each VNIC interface.<br />
VNIC interfaces can be deleted by writing the name of the interface to the<br />
/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic file. For<br />
example, to delete interface veth0, run the following command (as a root user):<br />
echo -n veth0 ><br />
/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic<br />
