I managed to install a SAP APO (special R/3 version) on basis of SAP DB 7.3 with RAW devices. It even worked like it was explained in the documentation delivered by SuSE with the SLES-7 and together with the shipped 2.4.7-4GB kernel. It even works with a Volume Manager inbetween, altough this is not supported by SAP! The only Problem currently is, that you have to specify one page lesser than the theortical maximum number of pages you would get, when you devide the megabytes - listed in the LVM tool for the RAW device - by 8 kbytes pages. Specify this n-1 number when you try to create the devspaces. As far as I know, this page is needed for adminitration issues. So try it :-). So far I didn't get any database crash or similar for the last 6 weeks nonstop running.
