Thanks Jack, 
When I chown oracle:oinstall /dev/raw/raw1 a restart of rawdevices chowns it back to root:disk .

--
$ ll /dev/raw
total 0
crw-rw----  1 root disk 162, 1 May  8 13:02 raw1

$ service rawdevices restart
Assigning devices:
           /dev/raw/raw1  -->   /dev/sdp1
/dev/raw/raw1:  bound to major 8, minor 241
done

$ /etc/init.d/oracleasm createdisk VOL14 /dev/raw/raw1
Marking disk "/dev/raw/raw1" as an ASM disk: asmtool: Unable to open device "/dev/raw/raw1": Block device required [FAILED]

$ ls -ld /dev/raw
drwxr-xr-x  2 root root 60 May  8 13:04 /dev/raw


I get the same error if I change /dev/raw/raw1 to oracle:oinstall after restarting rawdevices then run oracleasm createdisk.
Also tried chmodding /dev/raw to 777 (to test) and we still get the same error.

Cheers,
Nick .
