5. Run the lsmod command to display loaded modules. You should have eight Quadrics loadable modules
installed.
# 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]
The sizes may differ from this output.
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
For Elan3 systems, use the elanprobe command to verify configuration information:
# elanprobe
NodeId 0
NumNodes 16
7. The Quadrics eip0 interface should be up. Use the ifconfig command to display the interface
network configuration:
# 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. You can find additional information about Quadrics in the /proc/qsnet directory. Use the find
command to display it:
# find /proc/qsnet -type f -print -exec cat {} \;
InfiniBand System Interconnect Troubleshooting
The following troubleshooting information applies to the InfiniBand system interconnects. Perform these steps
on any node on which you suspect a problem to determine if your HP XC system is configured properly. If
these tests pass but you are still experiencing difficulty, see Chapter 16.: Using Diagnostic Tools (page 149).
1. Run the /usr/mellanox/bin/vstat command to verify that the InfiniBand system interconnect is
connected and operating correctly:
# /usr/mellanox/bin/vstat
1 HCA found:
hca_id=InfiniHost0
vendor_id=0x02C9
vendor_part_id=0x5A44
hw_ver=0xA1
fw_ver=0x300000000
