HP XC System Software Administration Guide Version 3.2

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 {} \;
21.4.3 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 20: Using Diagnostic Tools (page 231).
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
num_phys_ports=2
port=1
port_state=PORT_ACTIVE
sm_lid=0x0001
port_lid=0x0002
port_lmc=0x00
max_mtu=2048
port=2
port_state=PORT_DOWN
sm_lid=0x0000
port_lid=0x0000
port_lmc=0x00
max_mtu=2048
2. Run the ib-setup command to verify that the configuration is correct. The output should
be similar to that in the following example:
# ib-setup
