ClusterPack V2.5 Release Note

Comprehensive Install Instructions

compute_config can be used to install IB drivers on Compute Nodes following a

Golden Image installation. This re-installation of the drivers will allow them to

work properly. To use the function, the IB driver bundle (i.e. IB4X-00) must be

swcopy'd into /var/opt/clusterpack/depot on the Management Server:

% /usr/sbin/swcopy -x enforce_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 install 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 that 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 reboot 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 15. Run finalize_config on the Management Server

Background

This step performs verification checks on the Cluster Management Software, and

validates the installation. It prints out diagnostic error messages if the installation

is not successful.

NOTE The finalize_config tool can be run at any time to validate the

cluster configuration and to determine if there are any errors in the

ClusterPack software suite.

Overview

This program verifies the Cluster Management Software and validates the

installation of the single Compute Node. If it reports diagnostic error messages,

repeat the installation process up to this point, performing all the steps in the order

specified.
