Hi Matt, Correct.. Its better to check it whether oracleasm service affects the DB :) However in all my current deployments I have used raw devices .. I have another doubt in this regard(may sound silly).. but Why can't the direct devices (soft links .. eg /dev/sdc, /dev/sdd) could be used for asm disks..????
