Host 컴퓨터에서 VM에 연결시킬 DATA와 Fast Recovery Area 디스크를 각각 10GB 사이즈로 생성합니다.

VirtualBox의 GUI 툴을 사용하여 생성해도 됩니다.

디스크 전체를 마운트 시킬 것 이므로 모두 단일 파티션으로 포맷합니다.

Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library
driver.  The following questions will determine whether the driver is
loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]').  Hitting <ENTER> without typing an
answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: grid

VM에 마운트된 디스크를 각각 ASM Disk로 할당해줍니다.

순서대로 마운트가 되었다면, 왼쪽의 명령으로 디스크를 생성하면 됩니다.
