	Can you strace the program? 

[root at host bin]# strace -f -o /tmp/log usr/sbin/asmtool -C -l /dev/oracleasm -n VOL1 -s /dev/vpathaa1

	I wonder if the vpath code doesn't honor the HDIO_GETGEO
ioctl(2), which is how "partitioness" is determined.  There should be
two calls to ioctl(2) in that log.  One will be LOOP_GET_STATUS, which
should fail, and the other will be HDIO_GETGEO.  If that's failing, it
explains a lot.
	If that is the case, IBM will have to fix their driver (don't
worry, I can help you work around it for now).
