RAC - VMware 환경, RAC 모드일때 디스크 추가하기

VMware 환경, RAC 모드일때 디스크 추가하기


1. VMware에서 하드디스크 추가할때
 1) Mode 선택 : Independent(체크), Presistent(선택)
 2) Store virtual disk as a sngle file로 생성하기

2. 디스크 생성완료후 해당디스크 Advanced 메뉴 선택
 1) Virtual device node 선택해주기 : SCSI 1:n(적당한노드선택)
 2) Mode가 Independent, Presistent 선택되어있는것 확인하기

3. rac1.vmx 파일 메모장으로 편집
 1) 해당 노드에 다음문구 추가
    scsi1:n(위에서 선택했던 노드번호).deviceType = "disk"

ex)

fileSearchPath = "D:\오라클공부\VMinstall\raw\storage;."

checkpoint.vmState = ""

scsi1:3.present = "TRUE"

scsi1:3.fileName = "bakdisk2.vmdk"

scsi1:3.mode = "independent-persistent"

scsi1:3.deviceType = "disk"

 2) 저장 후 부팅하기

4. 리눅스 상에서 fdisk, mkfs, mount 하여 사용하면 된다.

Disk /dev/sde doesn't contain a valid partition table

[root@rac2 ~]# fdisk /dev/sde
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.
 
 
The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
