Troubleshooting VirtualNIC and VIO Hardware
Issues
To verify that an InfiniBand host can access an Ethernet system through the EVIC,
issue a ping command to the Ethernet system from the InfiniBand host. Make
certain that the route to the Ethernet system is using the VIO hardware by using
the Linux route command on the InfiniBand host, then verify that the route to the
subnet is using one of the virtual Ethernet interfaces (i.e., an EIOC).
NOTE:
If the ping command fails, check the following:
• The logical connection between the InfiniBand host and the EVIC
Checking the logical connection between the InfiniBand Host and the
VIO hardware.
• The interface definitions on the host Checking the interface definitions
on the host.
• The physical connection between the VIO hardware and the Ethernet
network Verify the physical connection between the VIO hardware and
the Ethernet network.
Checking the logical connection between the InfiniBand Host
and the VIO hardware
To determine if the logical connection between the InfiniBand host and the VIO
hardware is correct, check the following:
• The correct VirtualNIC driver is running.
• The /etc/infiniband/qlgc_vnic.cfg file contains the desired
information.
• The host can communicate with the I/O Controllers (IOCs) of the VIO
hardware.
