Troubleshooting VirtualNIC and VIO Hardware
Issues
To verify that an IB host can access an Ethernet system through the EVIC, issue a
ping
command to the Ethernet system from the IB host. Make certain that the
route to the Ethernet system is using the VIO hardware by using the Linux
route
command on the IB host, then verify that the route to the subnet is using one of
the virtual Ethernet interfaces (i.e., an EIOC).
Checking the logical connection between the
IB Host and the VIO hardware
To determine if the logical connection between the IB 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.
NOTE
If the
ping
command fails, check the following:
 The logical connection between the IB host and the EVIC Checking the
logical connection between the IB 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 .
