Issue: Device eth0 does not seem to be present, delaying initialization

Postby mintaka » 2017/09/09 05:33:39

Hello,
We are facing issue with our Centos server its networking died and when we try to restart it gives error "Device eth0 does not seem to be present, delaying initialization"

ifconfig shows only l0 and no eth0
but eth0 exists and few add on ips configured as eth0:x

Googled the issue and only resolution we found was "Delete networking interface rules file so that it can be regenerated and reboot your CentOS system.

# rm /etc/udev/rules.d/70-persistent-net.rules
# reboot"

But it still do not work. Any idea what is causing it and how to fix it?

Thanks in advance

Run lspci -nn|grep net to see if the OS sees the NIC.
Look at /etc/sysconfig/network-scripts/ifcfg-eth0 and see if it looks ok.

It was working server. lspci command not found and everything seems ok in the ifcfg-eth0 file.

server is in datacenter and we only have IPMI. Network is not working so we cannot install anything via yum :(

"ifconfig" or "ifconfig -a"?

If "ifconfig", then try adding the "-a" switch.

Is there anything related to networking or eth in /var/log/boot.log

Ifconfig -a switch shows only l0 interface details.
I checked boot log and for eth0 it shows "Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization"
:(

Then the driver for your network card is not loading. If you know what model it is and which driver it uses you can try manually loading it using modprobe. The easiest way to find that is to run lspci and if your server is really a server then it's likely to have an IPMI interface of some sort and many of those have the ability to remotely mount iso images. If you can do that then you can attach the CentOS media to it, mount it, navigate to the Packages directory and install pciutils from there. If it doesn't appear in the output of lspci then it sounds like the netword card is toast - or perhaps someone disabled it in the BIOS?

As simple alternative to lspci you can try

Code: Select all

cut -f1,2,18 /proc/bus/pci/device


Also look at output of dmesg you should see your card there.
