Problem with ASM disks (virtual)

__OUTSIDER___Jun 19 2012 — edited Jun 29 2012
Hi dear ASM experts.
Please help me to understand why runcluvfy.sh tell me that my ASM disks are not shared on all nodes .
My configuration.

PRVF-5149 : WARNING: Storage "/dev/oracleasm/disks/OCRASM2" is not shared on all nodes
PRVF-5149 : WARNING: Storage "/dev/oracleasm/disks/OCRASM1" is not shared on all nodes
PRVF-5149 : WARNING: Storage "/dev/oracleasm/disks/OCRASM0" is not shared on all nodes
It is normal behavior that runcluvfy.sh discovered /dev/xvdc and not /dev/xvdc1 .... ?

In my understanding everything is done correctly but still I got warnings.....

./thanks
