Required NIC Interface Naming Convention

Required NIC Interface Naming Convention

Product Line:  VERDE

Specific to VERDE (rpm's), the Network Interface must be named the same across all VERDE servers.

Installing with VERDE rpm's, CENTOS 7.x takes liberties and renames the NIC.  Here are instructions on how to configure the name to:  etho.


The old naming convention:

To restore the old naming convention, you need to edit the /etc/default/grub file and add net.ifnames=0 biosdevname=0 at the end of the GRUB_CMDLINE_LINUX variable.  The modified line should look as follows:

GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0"


Then, test the new configuration to see if no mistake has been made:
# grub2-mkconfig

When the aforementioned runs properly, you'll see a Done

If everything is fine, update the grub2 configuration:

# grub2-mkconfig -o /boot/grub2/grub.cfg

done


Update the network interface configuration file (here the initial interface name was enp2s0 and the new one is eth0):

# cd /etc/sysconfig/network-scripts
# cp ifcfg-enp2s0 ifcfg-eth0

Edit the ifcfg-eth0 file and replace the network interface name in the NAME variable with “eth0“.

After a reboot, everything should be OK.


If VERDE was already installed, rerun the VERDE configuration as follows:

/usr/lib/verde/bin/verde-config -i
