5 – Software Installation OpenFabrics Drivers and Services Configuration and Startup

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:

# 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:

#echo -n veth0 >

/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic

More information for configuration, starting and stopping the interface, and basic troubleshooting is available in the QLogic OFED+ User Guide.

OpenSM

OpenSM is an optional component of the OpenFabrics project that provides a subnet manager for InfiniBand networks. You do not need to use OpenSM if any of your InfiniBand switches provide a subnet manager, or if you are running a host-based SM.

After installing the opensm package, OpenSM is configured to be on after the next machine reboot. Install OpenSM on the machine that will act as a subnet manager in your cluster, or if it has been installed on more than one machine, use the chkconfig command (as root) to disable it on all the nodes except for the one on which it will be used. Use this method:

#chkconfig opensmd off

The command to enable it on reboot is:

#chkconfig opensmd on

You can start opensmd without rebooting your machine by typing:

#/etc/init.d/opensmd start

You can stop opensmd again like this:

#/etc/init.d/opensmd stop

If you want to pass any arguments to the OpenSM program, modify the following file, and add the arguments to the OPTIONS variable:

/etc/init.d/opensmd
