1.OCI 콘솔에서 앞서 Attach된 Block Volume의 Device Path(/dev/oracleoci/oraclevdb)를 확인할 수 있습니다.

볼륨을 인스턴스에 연결하고 scsi명령을 수행한다.

2.Device Path를 확인합니다.

[opc@examplelinuxinstance ~]$ ls -la /dev/oracleoci/

lrwxrwxrwx.  1 root root    6 Jan 10 07:35 oraclevdb -> ../sdb

3.마운트 할 디렉토리 생성

sudo mkdir /mnt/maro

4./etc/fstab 업데이트

sudo vi /etc/fstab
