Re: unable to add disks to asm diskgroup

Hi Mohan,

Good to see your problem is solved. 

Out of curiosity, may I ask why you explicitly set asm_diskstring when you are 
using asmlib? It should have been sufficient to leave it to the empty string, 
or alternatively set to 'ORCL:*'.

You might notice that your library in v$asm_disk is not ASMLib, but system. As 
far as I know this is not a problem since you still use direct IO.

Best regards,

Martin

Thanks Kjetil. It was something to do  with ASM_DISKSTRING parameter which
was supposed to be

/dev/oracleasm/disks/* and not /dev/oracleasm/disks

Its working now!
