Quadrics QsNetII Interconnect

Postinstallation Configuration and Testing

This manual describes how to service HP Cluster Platforms employing the

Quadrics

QsNetII™ Interconnect. It also describes basic diagnostic procedures

you can use to find out whether or not you have correctly configured the components

of the cluster and also to troubleshoot the cluster.

The first diagnostic that you will perform is a post-installation verification of the

assembled cluster. To do this, it is necessary that you perform some operations

without a complete explanation and understanding of the diagnostic tools and

procedures. However, you will use many of the same tests and procedures when

maintaining your cluster, and detailed explanations are provided in following

sections and chapters.

________________________ Caution _______________________

If you are performing initial configuration and postinstallation

verification of an HP Cluster Platform, you must perform all the

procedural steps in all sections of this chapter.

The following topics are described in this chapter:

• An overview of the interconnect diagnostics, (see Section 9.1).

• Preparing to run the postinstallation verification, (see Section 9.2).

• Verifying or changing the controller card settings, (see Section 9.3).

• The postinstallation verification procedure, (see Section 9.4).

• The diagnostic procedural flowchart Section 9.5.

9.1 Overview of the Diagnostics

The interconnect test and diagnostic software is provided as part of the operating

environment software and includes an interactive ROM-based firmware that is

preinstalled on each interconnect’s controller card. It enables you to identify faulty

components in an interconnect network and to ensure that the cluster configuration

is operating as designed. The software diagnostics described in the following

chapters apply only to HP Cluster Platforms running the HP XC operating

environment. It is assumed that you have completed the installation of HP XC and

configured the operating environment as described in the Administration Guide

for the HP XC Operating environment. Additional diagnostic tests and procedures

might be provided in the HP XC documentation.

This manual covers diagnostics, performance analysis, and troubleshooting for

the following cluster components only:

• The cluster interconnect hardware and its installed modules, such as switch

cards and controller cards.

• The QM500 PCI card installed in cluster nodes.

• Links (physical and logical) within the interconnect, and between the

interconnect and the cluster nodes via the QM500 card.

• The entire high-speed network between all nodes connected to the interconnect

hierarchy.
