Tip:
After creating the interfaces, you can run the ifconfig command with the -
a option to verify the MAC address on the compute node. For example, to
verify the new interface and its MAC address, run the following command on
the Oracle Linux compute node for which the VNIC was created:
# ifconfig -a eth4
The output of this command shows the HWADDR, which is the MAC address
you defined for the VNIC in Step 5.
On the compute node, run the following command to display the list of VNICs
17.
available on the compute node:
el01cn01# mlx4_vnic_info -l
This command displays the name of the new interface, as seen on the compute
node, such as eth4. Note this ID.
Create another VNIC for the same compute node, but using a connector on a
18.
different gateway switch. Note the ethX ID of this VNIC too.
It is recommended that you configure the two EoIB interfaces as a bonded
interface, such as bond1.
Create interface files for the VNICs on the compute node.
19.
To ensure correct failover behavior, the name of the VNIC interface file and the
value of the DEVICE directive in the interface file must not be based on the kernel-
assigned ethX interface name (eth4, eth5, and so on). Instead, Oracle
recommends that the interface file name and value of the DEVICE directive in the
interface file be derived from the EPORT_ID and IOA_PORT values, as follows:
Note:
Any other unique naming scheme is also acceptable.
Run the following command to find the EPORT_ID:
a.
#mlx4_vnic_info -i ethX | grep EPORT_ID
Example:
e101cn01#mlx4_vnic_info -i eth4 | grep EPORT_ID
EPORT_ID 331
Note the EPORT_ID that is displayed, 331 in this example.
Run the following command to find the IOA_PORT:
b.
#mlx4_vnic_info -i ethX | grep IOA_PORT
