RHEV 4.1 and Oracle ASM

We're looking to migrate from VMware to RHEV for certain Oracle RAC databases but I'm not seeing a way to mark a UUID to the shared disks. In VMware you just set "disk.enableUUID=true" and then from the OS you can run "/sbin/scsi_id -g -u -d /dev/sdX" to find the UUID. In fact, looking at a udev rule on one of our VMware RAC DB's I see something like the following:

KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="36000c295d87469d6252afa01e5341691",NAME+="oracleasm/disks/DATA_1" OWNER="oracle" GROUP="oinstall" MODE="0660"

Since I can't see a way to enable UUID on the RHEV disks, the command "/sbin/scsi_id -g -u -d /dev/$parent" will fail. Is there a way to enable UUID in RHEV or do we have to use another method to create the ASM disks.
Thank you,
