Suse Enterprise upgrade from 11 SP4 to 12 SP3 – Error with LVM partitions

If you’re upgrading from Suse Enterprise Server 11 SP4 to 12 SP3 and you get this error:

Some partitions in the system on /dev/XdYZ are mounted by kernel-device name. This is not reliable for the update since kernel-device names are unfortunately not persistent. It is strongly recommended to start the old system and change the mount-by method to any other method for all partitions.

Follow the Suse kb 7003734:
