HP XC System Software Administration Guide Version 2.1

5. Run the lsmod command to d isplay loaded modules.
There should be eight Quadrics
loadable m od ules installed. The reported size
s can vary.
# lsmod
jtag 30016 0 (unused)
eip 86856 1
ep 821112 9 [eip]
rms 48800 0
elan4 466352 1 [ep]
elan3 606676 0 [ep]
elan 80616 0 [ep elan4 elan3]
qsnet 101040 0 [eip ep rms elan4 elan3 elan]
6. For Elan4 systems, use the qsnet2_probe command to verify configuration information
including the NodeId:
# qsnet2_probe
Mode Switched
NodeId 10
NumLevels 2
NumNodes 16
# elanprobe
NodeId 0
NumNodes 16
7. The Quadrics eip0 interface should be up . Use t he ifconfig command to display the
interface network c onfig uration :
# ifconfig eip0
eip0 Link encap:Ethernet HWaddr 00:00:00:00:00:0A
inet addr:172.22.0.1 Bcast:172.22.255.255 Mask:255.255.0.0
UP BROADCAST RUNNING MULTICAST MTU:65264 Metric:1
RX packets:88 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:7 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:3696 (3.6 Kb) TX bytes:0 (0.0 b)
You can try to ping other nodes that are connected to the network.
8. Make sure that the nodes are wired to the Quadrics switches in the correct order. See the
HP XC Hardware Preparation Guide for additional information.
9. There is additional information about Quadrics under the /proc/qsnet directory. Use
the find command to display it:
# find /proc/qsnet -type f -print -exec cat {} \;
16.1.3 InfiniBand Troubleshooting
The following troubleshooting information applies to th e InfiniBand system interconnects;
perform the se steps on any node wh ich you suspect a problem to determine if your HP XC
system is configured properly. If theses tests pass but you are still experie ncing difficulty,
see Chapter 15.
1. Run the /usr/mellanox/bin/vstat command to verify that the Infi niBand board is
connected and operating correctly.
# /usr/mellanox/bin/vstat
