hi i m new to oracle rac,

and i wish to instlall 11g r1 RAC on my laptop having linux 4 as platform (on vmware) ,
for that i prepare 4 partition for that (on node1)

/dev/sdb1 - for ocr
/dev/sdb2 - for voting disk
/dev/sdb3 - for asmdisk group
/dev/sda5 - fro asmdisk group

by assuming external redundacy for ocr and voting disk i kept only one disk

and i configured following in /etc/sysconfig/rawdevices
/dev/raw/raw1 /dev/sdb1 -- ocr
/dev/raw/raw2 /dev/sdb2 -- voting disk
/dev/raw/raw3 /dev/sdb3 -- asmdisk group
/dev/raw/raw4 /dev/sdb5 -- asmdisk group


and my question is how node2 can understat these raw device as shared storage?
thanks for any support
