Please advice, what should be the next step and how to move forward?
Thanks in advance.

Can you verify that the physical disks allocated to ASM have the write permission ownership granted to Oracle user?  This is a common thing that can go wrong setting up ASM.

I'm not sure exactly what is the problem, but this article goes step by step through the prerequisite /etc/sysconfig/rawdevices settings and chown oracle ownership on the raw devices, as well as the oracleasm.

http://www.rampant-books.com/art_hunter_rac_oracle_asm_automatic_storage_management.htm

One of the points mentioned there, perhaps worthy to try, if this is of course a new database you are setting up, and there is no data of value present anyway, then just try to delete and recreate any problem disks again...

oracleasm deletedisk DATA1
oracleasm createdisk DATA1 /dev/????

And about filling in the ???? part, if you just cd /dev and then look for devices that have disk or dsk in the name, you should see the raw devices that correspond to your known hardware.

On AIX, I see disks raw device name like /dev/hdisk9, and then I want to see "ls -l" on that device and see that Oracle owns it and has write permission on it (the chown step in the article as above).
