Oracle RAC - ASM Verification Fails before Clusterware installs

Currently Being Moderated
I am new to Oracle RAC, i am preparing for installing Oracle Clusterware , after that i will installing Oracle RAC DB.
Oracle Database 11g Release 2 Grid Infrastructure (11.2.0.1.0) for Linux x86-64
Oracle Database 11g Release 2 (11.2.0.1.0) for Linux x86-64

Node-1 (Created ASM disks in this node)
[root@node1 grid]# oracleasm listdisks
DATA1
DATA2
DATA3
[root@node1 grid]#


Node-2 (In this node i just did "oracleasm scandisks")
[root@node2 grid]# oracleasm listdisks
DATA1
DATA2
DATA3
[root@node2 grid]#

But when i run "runcluvfy" with the following option :
sh ./runcluvfy.sh stage -pre crsinst -n node1,node2 -r 11gR2 -asm -asmdev /dev/sdb1,/dev/sdc1,/dev/sdd1 -verbose

I am getting the following errors:

Checking Devices for ASM...

ERROR: /dev/sdb1
Unable to determine the sharedness of /dev/sdb on nodes:
node1,node2

ERROR: /dev/sdc1
Unable to determine the sharedness of /dev/sdc on nodes:
node1,node2

ERROR: /dev/sdd1
Unable to determine the sharedness of /dev/sdd on nodes:
node1,node2

Checking for shared devices...

PRVF-5149 : WARNING: Storage "/dev/sdb1" is not shared on all nodes
PRVF-5149 : WARNING: Storage "/dev/sdc1" is not shared on all nodes
PRVF-5149 : WARNING: Storage "/dev/sdd1" is not shared on all nodes
Result: Devices check for ASM failed

Can someone tell what i am missing here?
Thanks in advance for your time.
