Troubleshooting Acronis Backup and Recovery NIC detection issues
In some rare cases there can be some issues with network cards.
So here is the situation: You booted machine from Bootable Media and your NIC doesn't acquire DHCP address or doesn't enlisted as device
Follow step-by-step instructions below to troubleshoot the issue.
1. Check the most recent media available
First, try to check device work with the latest build of the bootable media, most probably it contains more drivers and problem may be already solved.
2. Check the current network state
- Swith to shell: navigate to Actions -> Start shell or hit Ctrl+Shift+F2 (Alt+F1 to return back to GUI).
- Issue #ifconfig -a and see which network cards are listed in the output if any.
3. Troubleshoot DHCP Issues
- Check that DHCP server is really active in the subnet where the machine is booted by issuing this command in the shell:
#asamba dhcp -n
If DHCP is detected the output will be similar to this:
If DHCP is not detected the output will be the following:
- If DHCP is not detected, you can specify the network settings manually (Actions -> Exit ->Configure Network):
- If specifying the network manually did not help, enable asamba logs as described in Acronis Linux Products: Collecting Asamba Verbose Logs in Linux
- And try to obtain DHCP lease once more:
#asamba dhcp -n
- Check the asamba log in /tmp/asamba.log for errors.
If the steps above have been executed and the issue still persists, collect the following information and contact Acronis Customer Central.
- System Report unde the bootable media. See Acronis Backup & Recovery 11.7/11.5 Generating System Report
- System Report under the operating system. Collect System Report from the machine in question: see instruction for Acronis Backup 11.7/11.5 Generating System Report, if this fails for any reason, you can use this AcronisInfo Utility
- Results of the performed troubleshooting steps.
- Whether the machine is physical or virtual.
- PCI ID of your NIC.
- Wheter DHCP is properly detected under the operating system.
4. Troubleshoot network card drivers issues
(!) Use the latest build of the bootable media
- Check if drivers were loaded successfully with the following command:
If drivers are loaded, the output will be similar to this:
00:05:0 10ec:8139 5853:0001 8139cp(the underlined part is the driver id)
If drivers are not loaded, the output will be similar to this (driver's id missing):
- Check dmesg for errors by issuing this command:
#cat var/log/messages | grep eth
If the drivers are not loaded, collect the following information and Acronis Customer Central.
- Model of your NIC.
- System Report under the bootable media. See Acronis Backup 11.7/11.5 Generating System Report.
- Let us know if the NIC was detected by a previous build of the bootable media and collect System Repot under this media.
As an alternative, you may use a Windows-based Bootable Media (WinPE) - see Acronis Bootable Media Types. It uses Windows-based drivers which can be requested from the respective hardware vendor and embedded into WinPE-based media manually.
