device eth1 does not seem to be present delaying initialization

Question

What are some potential causes of the error message "device eth0 not found" and how can it be resolved?

Answer 1

The error message "device eth1 does not seem to be present delaying initialization" typically indicates that the system is unable to find the network interface card (NIC) with the name "eth1". This could be due to a few reasons:

1. The NIC driver is not installed or not functioning properly.
2. The NIC is physically not present or not properly connected.
3. The NIC has been renamed to something other than "eth1".
4. The NIC has been disabled in the system BIOS.

To troubleshoot this issue, you can try the following steps:

1. Check if the NIC driver is installed using the command "lspci -v". Look for the network adapter in the output and check if it has a driver loaded. If the driver is not loaded, you can try loading it manually using the "modprobe" command.

2. Check if the NIC is physically present and properly connected. You can open the system and check if the NIC is properly seated in the PCI slot and connected to the network cable.

3. Check if the NIC has been renamed to something other than "eth1". You can use the command "ip link show" to list all the network interfaces on the system and look for the interface name that corresponds to the NIC.

4. Check if the NIC has been disabled in the system BIOS. You can reboot the system and enter the BIOS settings to check if the NIC is enabled.

If none of the above steps resolve the issue, you may need to replace the NIC or consult with a network administrator for further assistance.

Answer 2

Yes, it is possible that the error "device eth1 does not seem to be present delaying initialization" could be caused by migration, especially if the migration involved moving the system to a new hardware platform or network environment. During migration, it is possible that the NIC drivers or configuration settings were not properly migrated or set up for the new environment, resulting in the error message.

To resolve the issue, you can try the following steps:

1. Check if the NIC driver is installed and functioning properly on the new hardware platform using the command "lspci -v".

2. Check if the NIC configuration settings are set up properly for the new network environment. You can check the configuration files under "/etc/network/interfaces" and verify if the settings are correct.

3. Check if the network cable is properly connected to the NIC on the new hardware platform and if the network switch is properly configured to recognize the NIC.

4. If the NIC is not recognized at all, you may need to manually install the NIC driver for the new hardware platform or network environment.

5. If all else fails, you may need to consult with a network administrator or technical support for further assistance in resolving the issue.

Overall, migration can often result in unexpected issues, and it is important to carefully test and verify all settings and configurations to ensure a smooth transition to the new environment.

In my case, it was mac address issue, I fixed it by removing and added a new address

Answer 4

removed the mac address and restarted networks, works for me
