Adding the oracle-user to the disk group is not a good idea anylonger.
Running RAC and after installing e.g. CRS-patch 5256865 Oracle will give
you permission-errors accessing the voting disk even with oracle being
in the disk-group. The correct way of doing it is to adjust
/etc/udev/udev.permissions.

e.g. for the raw devices and sdb:

raw/raw*:oracle:oinstall:660
sdb*:oracle:oinstall:660
