1. 我在这创建5个磁盘 cd C:\Program Files\Oracle\VirtualBox VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm1.vdi -size 5120 -format VDI -variant Fixed VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm2.vdi -size 5120 -format VDI -variant Fixed VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm3.vdi -size 5120 -format VDI -variant Fixed VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm4.vdi -size 5120 -format VDI -variant Fixed VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm5.vdi -size 5120 -format VDI -variant Fixed 2. 在Oracle VM中附加进去。 这个VM也可以用命令，但不太好使。 Settings -> Storage->Controller:SATA ->Add Hard Disk 3. 更改成共享模式 VBoxManage.exe modifyhd D:\OracleVM\ASM\asm1.vdi --type shareable VBoxManage.exe modifyhd D:\OracleVM\ASM\asm2.vdi --type shareable VBoxManage.exe modifyhd D:\OracleVM\ASM\asm3.vdi --type shareable VBoxManage.exe modifyhd D:\OracleVM\ASM\asm4.vdi --type shareable VBoxManage.exe modifyhd D:\OracleVM\ASM\asm5.vdi --type shareable 4. 检查下状态 a. VBoxManage list vms b. 进入linux 系统 [root@rac1 dev]# ls sd* sda sda1 sda2 sdb sdc sdd sde sdf //其中 sdb sdc sdd sde sdf 就是挂上的那5个盘
5. 来fdisk 磁盘。 依次: fdisk sdb fdisk sdc fdisk sdd fdisk sde fdisk sdf 附了个例子: [root@rac1 dev]# fdisk sdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0x1f132726. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable. Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u').

Calling ioctl() to re-read partition table. Syncing disks. [root@rac1 dev]# ls sd* sda sda1 sda2 sdb sdb1 sdc sdd sde sdf
6. 依次创建asm磁盘 [root@xclrac1 ~]# oracleasm createdisk DISK1 /dev/sdb1 Writing disk header: done Instantiating disk: done [root@xclrac1 ~]# oracleasm createdisk DISK2 /dev/sdc1 Writing disk header: done Instantiating disk: done [root@xclrac1 ~]# oracleasm createdisk DISK3 /dev/sdd1 Writing disk header: done Instantiating disk: done [root@xclrac1 ~]# oracleasm createdisk DISK4 /dev/sde1 Writing disk header: done Instantiating disk: done [root@xclrac1 ~]# oracleasm createdis
