Example:
cp /etc/sysconfig/network/ifcfg-em3 /etc/sysconfig/network/ifcfg-em4
echo DEVICE=em3 > /etc/sysconfig/network/ifcfg-emX
echo STARTMODE=onboot >> /etc/sysconfig/network/ifcfg-emX
echo USERCONTROL=no >> /etc/sysconfig/network/ifcfg-emX
echo BOOTPROTO=static >> /etc/sysconfig/network/ifcfg-emX
echo NETMASK=X.X.X.X >> /etc/sysconfig/network/ifcfg-emX
echo IPADDR=X.X.X.X >> /etc/sysconfig/network/ifcfg-emX
echo 1 >/sys/bus/pci/rescan
sleep 2
ifup emX
7. Configure the default gateway:
echo "default <XXX.XXX.XXX.XXX> - em3 " >/etc/sysconfig/network/ifroute-emX
For example:
echo "default - em3" > /etc/sysconfig/network/ifroute-em3
Note: Only the one default gateway is required. Most likely this will be the management network interface.
Create this file by using the following command:
touch /etc/sysconfig/network/ifroute-emX
8. Perform reboot to the host.
9. After the host is up, log in to the management IP address using SSH, and ping all data IP addresses of another
node to make sure that you have the correct connectivity on each node.
