HP XC System Software Installation Guide Version 3.0

Appendix D Configuring Interconnect Switch Monitoring
Cards
You must configure the Quadrics switch controller cards, the InfiniBand switch controller cards, and the
Myrinet monitoring line cards on the system interconnect in order to diagnose and debug problems with the
system interconnect.
Perform one of the following procedures to configure these cards just before running the cluster_config
command:
• Configuring the Quadrics Switch Controller Card (page 105)
• Configuring the Myrinet Switch Monitoring Line Card (page 108)
• Configuring the InfiniBand Switch Controller Card (page 109)
Note
You must reconfigure the switch monitoring line cards any time you change your system configuration and
then rerun the discover command.
Configuring the Quadrics Switch Controller Card
The Quadrics switch controller card provides access to Quadrics switch control functions through an Ethernet
connection. The controller card runs a process that collects configuration and status information from the
switch.
Table D-1 and Table D-2 provide the switch names and associated IP addresses you need for the
configuration procedure. The IP addresses for the switch monitoring line cards is based on the swBase
address in the base_addr.ini file. The default address base for the switch monitoring line cards is
172.20.66, but if you modified the swBase value, the address base for the switch monitoring line cards
must change accordingly.
