Hi Scott, This weblink may help --> http://www.ardentperf.com/2008/02/13/oracle-clusterware-on-rhel5oel5-with-udev-and-multipath/ I've not tried this, but the author of the article claims that it works.. We are also facing similar issue(s) with Oracle and RHEL 5.1 using UDEV/Device-mapper..I've also posted a query on the same (https://www.redhat.com/archives/dm-devel/2008-February/msg00201.html) ...But it just discusses the changing of permissions, however creation of raw devices using UDEV is not specified, hence we are still looking for that answer. Hope it helps somewhat. Let us know.
