Correlating 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 Linux nodes.
About this task
RHEL 7.x does not use the 70-persistent-net.rules file for Ethernet
persistency. Instead, in RHEL 7.x nodes, the interface names are in the following
format: enXXX (for example: enp6s0f0 or eno3).
Note:
In the following procedure, the commands are being run on a RHEL 7.x
node, so the example outputs include interface names in the format enXXX.
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
