    Oracle RAC - ASM Verification Fails before Clusterware installs

    ZachIN
      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/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.
