Steps to create raw device for vd,ocr and asm
we have already created vd partition at os level
vd.vmdk file which is vd disk addition to vmware
after adding vd datastore to vmware

remember we are using seperate partitions starting from host to vm machine level
in order to create raw device for vd we need to edit the 60-raw.rules file and this file is available at /etc/udev/init.d folder
this file contain already a commented line which help you just copy and paste it to bottom and alter the required
I am doing the below for my sdb,sdc and sdd which I have added for vd,ocr and asm
the line to be added is
ACTION=="add",KERNEL=="sdb",RUN=="/bin/raw /dev/raw/raw1 %N"
ACTION=="add",KERNEL=="sdc",RUN=="/bin/raw /dev/raw/raw2 %N"
ACTION=="add",KERNEL=="sdd",RUN=="/bin/raw /dev/raw/raw3 %N"

at the end we are chaning default permissions and owner of raw device
by adding one more line
ACTION=="add",KERNEL=="raw*",OWNER=="oracle",GROUP=="oinstall",MODE=="0770"
you can give for ocr raw device root as user
do the same on node1 and node2
then use /bin/start_udev command which start your udev
and question the raw devices available with major and minors
raw -qa
checking the output for all the devices added carefully
