Is the root file system part of the VG? If so, simply running dasd_configure now will not be sufficient. You will also have to update the initrd that you will be using. The command to do that is dracut, see man 8 dracut for that. SUSE also provides a compatibility wrapper for dracut that takes the place of the old mkinitrd command. You can check the results by using the lsinitrd command to see if the udev rule for the new DASD volume is present. For those that don't want to develop a detailed checklist/process document for doing things like this, this is why SUSE has YaST. We try very hard to ensure that system administrators that use YaST get the results they expect without having to know all the nitty gritty low-level details. Those that have a handle on those details, are free not to use YaST, of course.
