Summary
Network is unreachable after Live BMR restore to SLES 10 machine. To resolve this issue, ensure the driver is present on the restored machine and then the network becomes reachable.
Resolution
If the network is unreachable after a Live BMR restore to a SLES 10 machine, the driver was not loaded by Linux even though it may be present on the restored machine.
To identify the name of the driver, login as root and run the following command:
lscpci -k >/tmp/lspci-k.out
Edit the file /tmp/lspci-k.out and search for the string: "Ethernet controller:"
This line identifies the name of the network card. The network drivers for the controller are listed underneath. The value of the Kernel modules: key has the name of the driver, e.g., tg3. Use this name in the command sequence below:
modprobe tg3
service network restart
If the driver is present on the restored machine, the network becomes reachable. If there is more than one Ethernet controller and each one has a different driver, then use either one.
