Note:
Two or more PCIe slot-based NICs are supported.
Correlate the PCI slot locations and interface names
Gather and correlate PCI slot locations and interface names in order to build a table
with the relevant interface names for the Linux nodes.
About this task
RHEL 7 does not use the 70-persistent-net.rules file for Ethernet persistency.
Instead, in RHEL 7 nodes, the interface names are in the following format: enXXX (for
example: enp6s0f0 or eno3).
Procedure
1. Find the correlation between physical slot names and interface names so that
you can discover the correlation between PCI slot locations and interface
names in the operating system:
Note:
For each of the following commands, write down the output and set it
aside for use later in this task:
a. Correlate the physical PCIe slot to a logical bus address:
dmidecode -t slot |egrep "Designation|Current Usage|Bus
Address"
This command displays the PCI location of each PCIe card. In the following
sample output, the logical bus address in the last three lines is
"0000:05:00.0," which is shown as Current Usage: In Use and
correlates to physical PCIe card slot location "PCIe Slot 6."
In this case, the 10GB PCI NIC is presented on slot 6, and the logical bus
address of its ports is 5:0 and 5:1. (See the "Correlating physical slot and
Ethernet network names" figure, in which the correlation between PCIe slot
and the logical bus address is highlighted in yellow.)
Designation: PCIe Slot 1
Current Usage: Available
Designation: PCIe Slot 2
