ClusterPack can configures IP over InfiniBand (IPoIB) if the appropriate InfiniBand drivers are installed
the systems.
Overview
If the InfiniBand IPoIB drivers are installed prior to running compute_config, the InfiniBand HCA is
detected and the administrator is given a chance to configure them.
The administrator can also configure the InfiniBand HCA with IP addresses by
invoking /opt/clusterpack/bin/clnetworks. See the man pages for clnetworks for usage instructions.
Known Issues
The is a known issue that IB drivers are not correctly configured following a Golden Image installation o
compute node.
compute_config can be used to install IB drivers on compute nodes following a Golden Image installatio
This re-installation of the drivers will allow them to work properly. To use the function, the IB dirver bu
(i.e. IB4X-00) must be swcopy'd into /var/opt/clusterpack/depot on the management server:
%
/usr/sbin/swcopy -x enfoce_dependencies=false -s <IB driver source> \*
@ /var/opt/clusterpack/depot
At the end of compute_config, if the IB drivers are found in /var/opt/clusterpack/depot, an option to inst
the IB drivers on the compute nodes will be given. If you choose to install the IB drivers on the compute
nodes, a second option will be presented: The IB drivers can be installed on only those compute nodes th
already have the driver software installed, or the IB drivers can be installed on all the compute nodes.
Installing the IB drivers requires the compute nodes to reboot. This erboot is done automatically by
compute_config as part of the installation.
Note:
If the IB drivers are installed on a compute node that does not have IB cards installed, the
MPI test in finalize_config will fail.

Step 16 Run finalize_config on the Management Server
Background
This step performs verification checks on the Cluster Management Software, and validates the installatio
rints out diagnostic error messages if the installation is not successful.
