6. Run the lsmod command to display loaded modules. You should have one Myrinet GM loadable
module installed.
# lsmod | grep -i gm
gm 589048 3
The size may differ from this output.
7. The Myrinet myri0 interface should be up. Use the ifconfig command to display the interface
network configuration:
# ifconfig myri0
myri0 Link encap:Ethernet HWaddr 00:60:DD:49:2D:DA
inet addr:172.22.0.4 Bcast:172.22.0.255 Mask:255.255.255.0

You can try to ping other nodes that are connected to the network.
20.4.2 Quadrics System Interconnect Troubleshooting
The following troubleshooting information applies to the Quadrics Elan4 and Elan3 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 19: Using
Diagnostic Tools (page 215).
1. Run the appropriate test for your system interconnect:
For Elan4 systems: qselantest -D 0
For Elan3 systems: elantest
2. Make sure that you are running an HP XC kernel, with Quadrics support. The HP XC kernels are
identified by the presence of XC in the kernel name:
# uname -a
Linux n16 2.4.21-15.7hp.XCsmp #1 SMP date ... GNU/Linux
3. Make sure that your system has Quadrics boards installed. The system shown in the following example
has both Elan3 and Elan4 boards; most systems have only one type.
# lspci -v | grep Quad
60:01.0 Network controller: Quadrics Ltd QsNet Elan3 Network Adapter (rev
01)
80:01.0 Network controller: Quadrics Ltd QsNetII Elan4 Network Adapter (rev
01)
4. Make sure that all the Quadrics RPMs are installed:
# rpm -q -a | grep qs
