I am in situation where the master bond0 interface is up but there is no IPv4 address assigned. I have the file correctly configured in /etc/sysconfig/network/bond0 and the slave interface eth4 and eth6 also showing up. But the bond0 not taking any IP ever after network restart.

I did Reboot and restart of interfaces. But after network restart it says 'no configuration found for ethx' for all interfaces and can not make the bond0 up showing 'interface bond0 not up'.

While I check lspci or hwinfo or /proc/net/dev I can see all network cards.

Now I am not sure why cannot get the IP up? Or how to check if any hw issue ?

I cannot include much configuration as that was my O&M interface and now accessing the server with console.

Can anyone help to understand ?
