Comprehensive Install Instructions

• A netmask

To define additional networks, use the command clnetworks. This tool is also

called from compute_config.

clnetworks provides a text-based interface for selecting nodes, network interfaces

and IP addresses. It guides the user through the creation of a network. It is also

possible to modify an existing network. When you have finished creating or

updating networks, clnetworks will ensure that each interface specified is

configured correctly and the proper entries exist in each host’s /etc/hosts file.

Overview

The compute_config program will register the nodes with various programs.

Details

Execute the following command.

% /opt/clusterpack/bin/compute_config

Step 14. Set Up InfiniBand (Optional)

Background

ClusterPack configures IP over InfiniBand (IPoIB) if the appropriate InfiniBand

drivers are installed on the systems.

ClusterPack provides a method to re-install the InfiniBand drivers on the Compute

Node using compute_config.

Overview

If the InfiniBand IPoIB drivers are installed prior to running compute_config, the

InfiniBand HCA is detected and the administrator is given a choice 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 of a Compute Node.
