VirtualNIC Interface Configuration and Administration
Failover to a port on a different Ethernet gateway
In this example, if the Ethernet port associated with iocguid 0x66a02de000048
(i.e., Ethernet port 2 on gateway 48) fails, then traffic going over eioc1 will begin
using Ethernet port 2 on gateway 03c. This type of failover allows traffic to
continue even if the entire gateway card fails or is rebooted. This type of failure
requires a second gateway card to be in the fabric.
NOTE:
In this example the same adapter port is being used for both the primary and
the secondary connection.
{CREATE; NAME="eioc1";
PRIMARY={ DGID=fe8000000000000000066a21de000048;
IOCGUID=00066a02de000048; INSTANCE=0; PORT=1; }
SECONDARY={ DGID=fe8000000000000000066a21de00003c;
IOCGUID=00066a02de00003c; INSTANCE=0; PORT=1; }
}
Combination method
In this example, if either the Ethernet port, the Ethernet gateway or the adapter
port fails, traffic using eioc1 will begin using Ethernet port 2 on gateway 03c via
adapter port 1.
{CREATE; NAME="eioc1";
PRIMARY={ DGID=fe8000000000000000066a21de000048;
IOCGUID=00066a02de000048; INSTANCE=0; PORT=2; }
SECONDARY={ DGID=fe8000000000000000066a21de00003c;
IOCGUID=00066a02de00003c; INSTANCE=0; PORT=1; }
}
Creating VirtualNIC Ethernet Interface Configuration Files
For each Ethernet interface defined in the /etc/infiniband/qlgc_vnic.cfg
file, create an interface configuration file:
For SuSE and SLES OS:
/etc/sysconfig/network/ifcfg-NAME
For RHEL OS:
/etc/sysconfig/network-scripts/ifcfg-NAME
where NAME is the value of the NAME field specified in the CREATE block.
