Oracleasm deletedisk failed with error:
/usr/sbin/oracleasm deletedisk DATA01 Disk "DATA01" defines an unmarked device Dropping disk: failed Unable to delete disk "DATA01"
Here I'll show you step by step how to solve this problem :
/usr/sbin/oracleasm deletedisk DATA01 Disk "DATA01" defines an unmarked device Dropping disk: failed Unable to delete disk "DATA01" -bash-3.2$ /usr/sbin/oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks...

Problem was that I tried to delete disk with grid user and it doesn't have permission to do that, therefore delete must use with root user.
