양쪽 rac1과 rac2 리눅스를 구동하고 공유디스크 format, ocfs설정 ,SSH 설정.

양쪽 rac1 리눅스와 rac2 리눅스를 구동하고나서 ping 제대로 나가는지 확인해본다.

아래모습을 보면 알겠지만.
설정한 public ip , private ip 는 ping 나가야하고.
virtual ip 는 아직 ping 이 나가면 안된다.

이제 설정한 공유디스크가 양쪽노드에 제대로 보이는지 확인하고 format 작업을 해준다.

양쪽에 이상없이 인식하는것을 확인했으면 둘중에 한곳에서 format 작업을 진행한다.

[root@rac1 ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

위와 같은 작업을 공유디스크가 4개이기때문에 4번을 반복한다.
물론 fdisk /dev/sdb <---- 각 디바이스 이름을 확인하고 모두 포멧을 해준다.
