Hi Anuj, Thank you for the post. I am having similar problem. I have my both parameters asm_diskgroups and asm_diskstring are set properly as follows
*.asm_diskgroups='SEDEVDATA','SEDEVFRA'
*.asm_diskstring='/dev/oracleasm/disks/*'

I don't have any problems while starting up the ASM instance but I am getting an error message while shutting down. I did not mount all the asm disks though, woudl that be a problem.

Thank you
