The first thing is to create physical partitions over your virtual SCSI devices. Actually this is not crucial for ASM installation because ASM can use physical disk as a whole without any partition. However if you wish to create ASMLIB you will need those partitions.

[root@localhost ~]# fdisk /dev/sda
