Re: Persistent change to use layer2 in SLES 11 SP4
If the only thing you want to change is the layer2 mode setting you can do this as root: cd /sys/bus/ccwgroup/drivers/qeth/ echo 0 > online echo 1 > layer2 echo 1 > online and the interface ought to come online with the same IP address as before. this will be temporary though and it will go back to L3 on reboot. at this point you can SSH in and use yast to fix it permanently.

Persistent change to use layer2 in SLES 11 SP4
Help! I have a dead network connection at a client and need to get it switched to layer2. What file do I have to change? I'd use yast, but I have no network connection with which to do so. Just the virtual machine console. I can see it trying to register layer 3 discipline, but this is (now) an ETHERNET mode VSWITCH. Thanks!
