Look at the qlgc_vnic.cfg.sample file to see how VNIC configuration

files are written. This file can be found with the OFED documentation, or in

the qlgc_vnictools subdirectory of the QLogicIB_Basic download. You

can use this configuration file as the basis for creating a configuration file by

replacing the destination global identifier (DGID), IOCGUID, and

IOCSTRING values with those of the EVIC/VEx IOCs present on your fabric.

QLogic recommends using the DGID of the EVIC/VEx IOC, as it ensures the

quickest startup of the VNIC service. When DGID is specified, the IOCGUID

must also be specified. For more details, see the qlgc_vnic.cfg sample

file.

3. Edit the VirtualNIC configuration file,

/etc/infiniband/qlgc_vnic.cfg. For each IOC connection, add a

CREATE block to the file using the following format:

{CREATE; NAME="eioc2";

PRIMARY={IOCGUID=0x66A0130000105; INSTANCE=0; PORT=1; }

SECONDARY={IOCGUID=0x66A013000010C; INSTANCE=0; PORT=2;}

}

a. Format 1: Define an IOC using the IOCGUID. Use the following format

to allow the host to connect to a specific VIO hardware card,

regardless of which chassis and/or slot the VIO hardware card resides:

{CREATE;

NAME="eioc1";

IOCGUID=0x66A0137FFFFE7;}

The following is an example of VIO hardware failover:

{CREATE; NAME="eioc1";

PRIMARY={IOCGUID=0x66a01de000003; INSTANCE=1; PORT=1; }|

SECONDARY={IOCGUID=0x66a02de000003; INSTANCE=1; PORT=1;}

}

NOTE:

The qlgc_vnic.cfg file is case and format sensitive.

NOTE:

Do not create EIOC names with similar character strings (for

example, eioc3 and eioc30). There is a limitation with certain

Linux operating systems that cannot recognize the subtle

differences. The result is that the user will be unable to ping

across the network.
