If you start the InfiniBand network stack separately, then the correct starting 
order is:

„

Start the InfiniBand stack.

„

Start QLogic VNIC service.

For example, if you use InfiniPath, the correct starting order is:

# /etc/init.d/openibd start
# /etc/init.d/qlgc_vnic start

The correct stopping order is:

„

Stop QLogic VNIC service.

„

Stop the InfiniBand stack.

For example, if you use InfiniPath, the correct stopping order is:

# /etc/init.d/qlgc_vnic stop
# /etc/init.d/openibd stop

If you try to stop the InfiniBand stack when the QLogic VNIC service is 
running, an error message displays, indicating that some of the modules of 
the InfiniBand stack are in use by the QLogic VNIC service. Also, any 
QLogic VNIC interfaces that you created are removed (because stopping 
the InfiniBand network stack unloads the Host Channel Adapter driver, 
which is required for the VNIC interfaces to be present).

In this case, do the following:

„

Stop the QLogic VNIC service by typing: 

„

Stop the InfiniBand stack again.

If you want to restart the QLogic VNIC interfaces, run the following 
command:

# /etc/init.d/qlgc_vnic restart

You can get information about the QLogic VNIC interfaces by using the following 
script (as a root user):

# ib_qlgc_vnic_info

This information is collected from the 
/sys/class/infiniband_qlgc_vnic/interfaces/ directory, under which 

there is a separate directory corresponding to each VNIC interface.

VNIC interfaces can be deleted by writing the name of the interface to the 
/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic file. For 

example, to delete interface veth0, run the following command (as a root user):

# echo -n veth0 > 
/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic
