OK - this error is absolutely ok - when editing bootargs via LAN the ethaddr cannot be changed - don't worry.
You are almost there
Next to do:
find the entries: bootargs_1, bootargs_2 and bootargs_3
in this long lines you find
Change it to:Code:root=/dev/sdb2 root=/dev/sdb3 root=/dev/sdb4
Apply changes, set your default image, reboot box - done!Code:root=/dev/sda2 root=/dev/sda3 root=/dev/sda4
