ASM Spfile on shared raw device

Question

Hi,
I am building two nodes Cluster on Linux 4 update 5. I have successfully created the CRS. Now I am trying to create the ASM instance using the ./dbca. When I select both nodes to manage diskgroup, during the instance creation, and after I enter the SPFILE file location, I am receiving this message
{The /dev/raw/raw10/spfile.asm.ora location is not valid. The directory "[/dev/raw/raw10/] is not a shared system partition across nodes1 and 2.}
The Oracle:dba has the ownership and read/write permission on this partition.
Your help highly appreciated.

Answer 1

1) Check to make sure that the partition /dev/raw/raw10 is a shared raw device between the nodes (you can do this by using: dd if=/dev/zero of=/dev/raw/raw10 bs=1M count=x from both the nodes while logged in oracle).
2) Since /dev/raw/raw10 is a raw device, you can not specify /dev/raw/raw10/spfile.asm.ora as an SPFILE location. Alternatively, under $ORACLE_HOME/dbs create a link to /dev/raw/raw10 with the name spfile$ORACLE_SID.ora from both the nodes.
ln -s /dev/raw/raw10 $ORACLE_HOME/dbs/spfile$ORACLE_SID.ora (both the nodes)
