I'm very new to sles 10; sounds like you want to do root-on-LVM-on-multipath I don't know if sles10 supports that. Maybe 2 things to try: (1) if /dev/rootVG/rootLV has a /dev/disk/by-id/ link then use that persistent name along with putting dm-multipath in INITRD modules list; then run mkinitrd and zipl (2) Or, use the LVM persistent name, /dev/rootVG/rootLV, instead of a /dev/disk/by-id/ name good luck. -------------------------------------------------------- This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.

In such I am not clear about what you are mentioning here.
