HP XC System Software Installation Guide Version 2.1

Determining the Network Type

The information in this appendix applies only to cluster platforms with a Quadrics QsNet

interconnect.

During the processing of the cluster_config comm and, the swmlogger gconfig

script prompts you to supply the netw ork type of your system. The network type describes the

topology of you r system, and it is used to create the qsnet diagnostics database. The Quadrics

diagnostic database utilities will not work properly if you specify an incorrect network type.

Quadrics currently supp orts the following network types: QMS8, QMS16, QMS32, QMS64,

QMS128, QMF2 56, and QMF10 24.

Follow this procedure to determine your network type:

1. View the following file to determine the NumLevels value:

# cat /proc/qsnet/elan4/device0/position

NodeId 7

NumLevels 2

NumNodes 16

2. Use the information shown in Table J-1 to determine your network type based on the

NumLevels value y ou obtained in the previo us step.
