VirtualNIC Interface Configuration and Administration
Link Aggregation Configuring
Troubleshooting
To configure link aggregation for all ports of a VIO hardware card, do the following:
1. Modify the chassis GUID and slot number.
2. Edit /etc/infiniband/qlgc_vnic.cfg file with information similar to
the following:
{CREATE; NAME="eioc1";
PRIMARY={IOCSTRING="Chassis 0x00066A0050000018, Slot
2, IOC 1"; }
SECONDARY={IOCSTRING="Chassis 0x00066A0050000018, Slot
2, IOC 2"; }
}
3. Create ifcfg-eioc1 file in directory
/etc/sysconfig/network-scripts.
4. Physically connect 2 or 3 ports of a VEx to an Ethernet switch.
5. Using the management interface for the Ethernet switch, configure the
switch to aggregate all 3 ports that connect to the VEx.
6. Restart the qlgc_vnic module with the following command:
/etc/init.d/qlgc_vnic restart
Refer to Appendix G for information about troubleshooting.
VirtualNIC Configuration Variables
NAME
The device name for the interface.
IOCGUID
Defines the port controller GUID to be used to identify the specific EVIC leaf
and port used by the VNIC. All of the IOC GUIDS detected on the fabric can
be found by typing ib_qlgc_vnic_query -e and noting the value of the
reported IOC GUIDs. This can be used instead of IOCSTRING.
IOCSTRING
Defines the IOC Profile ID String of the IOC to be used. All of the IOC Profile
ID Strings detected on the fabric can be found by typing
ib_qlgc_vnic_query -s and noting the value of the reported string. This
can be used instead of IOCGUID.
