The information in this appendix applies only
to cluster platforms with a QsNetII interconnect.
During the processing
of the cluster_config utility, the swmlogger
gconfig script prompts you to supply the network type of
the system. The network type reflects the maximum number of ports
the switch can support, and the network type is used to create the qsnet diagnostics database. The QsNetII diagnostic database utilities will not work properly if you specify
an incorrect network type.
QsNetII currently supports
the following network types: QMS8, QMS16, QMS32, QMS64, QMS128, QMF256,
and QMF1024, where the digits represent the maximum number of ports.
Follow this procedure to determine the network
type:
View the following file
to determine the NumLevels value:
# cat /proc/qsnet/elan4/device0/position
NodeId 7
NumLevels 2
NumNodes 16 |
Use the information shown
in Table H-1 to determine
the network type based on the NumLevels value you
obtained in the previous step and the maximum number of ports in the
switch.
Table H-1 Network Type Based on System Topology
| NumLevels Value | Network Type |
|---|
| 1 | QMS8 |
| 2 | QMS16 |
| 2 | QMS32 |
| 3 (this is a 64-way full bandwidth system) | QMS64 |
| 3 (this is a 128-way reduced bandwidth
system) | QMS128 |
| 4 | QMF256 |
| 5 | QMF1024 |
