RAC를 위한 Vmware 스토리지 추가하기

10GB만 추가해 보자.

첫번째 노드에서 하드디스크를 추가.

 

기존 4개디스크에서 더 추가를해서 5,6번이 생겼다.

그리고 scsi1:5.deviceType = "disk" 를 추가하고

각 4개노드의 vmx 파일에다가 다 추가를 한다.

 

scsi1:5.present = "TRUE"
scsi1:5.fileName = "M:\vm_asmdisk\disk5\asmdisk5.vmdk"
scsi1:5.mode = "independent-persistent"
scsi1:5.deviceType = "disk"

scsi1:6.present = "TRUE"
scsi1:6.fileName = "M:\vm_asmdisk\disk6\asmdisk6.vmdk"
scsi1:6.mode = "independent-persistent"
scsi1:6.deviceType = "disk"

 

부팅하하고

[root@rac1 ~]# fdisk -l

 

첫번째 추가된하드.

Disk /dev/sdg: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

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

 

두번째 추가된하드.

Disk /dev/sdh: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders

FDISK 로 Format 작업.
