首先是创建ASM磁盘组。
1、打开虚拟机添加SCSI控制器
2、增加磁盘，选择创建新的虚拟盘
3、选择磁盘文件类型，我这里选择默认第一个即可
4、选择固定大小磁盘
5、创建一块2G的磁盘
6、重复2-5上面创建磁盘的步骤分别创建asmdisk1-asmdisk8的8块磁盘，最终如下所示
9、启动虚拟机，使用root登录，首选需要安装oracleasm-support 插件，使用yum安装。
yum install kmod-oracleasm
10、使用fdisk 创建分区，fdisk /dev/sbd 到i按照如下 建立8个磁盘主分区
[root@12C ~]# fdisk /dev/sdi Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0x311a383f. 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'). Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-261, default 1): Using default value 1 Last cylinder, +cylinders or +size{K,M,G} (1-261, default 261): Using default value 261 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.11、分区完毕后初始化相关oracleasm参数，使用root用户执行oracleasm init
oracleasm init 12、配置oracleasm 的用户为oracle 和组为oinstall [root@12C ~]# oracleasm configure -i Configuring the Oracle ASM library driver. This will configure the on-boot properties of the Oracle ASM library driver. The following questions will determine whether the driver is loaded on boot and what permissions it will have. The current values will be shown in brackets ('[]'). Hitting <ENTER> without typing an answer will keep that current value. Ctrl-C will abort. Default user to own the driver interface [oracle]: Default group to own the driver interface [oinstall]: Start Oracle ASM library driver on boot (y/n) [y]: Scan for Oracle ASM disks on boot (y/n) [y]: Writing Oracle ASM library driver configuration: done 完毕后 [root@12C ~]# oracleasm createdisk ASMDISK1 /dev/sdb1 Writing disk header: done Instantiating disk: done [root@12C ~]# oracleasm createdisk ASMDISK2 /dev/sdc1 Writing disk header: done Instantiating disk: done [root@12C ~]# oracleasm createdisk ASMDISK3 /dev/sdd1 Writing disk header: done Instantiating disk: done [root@12C ~]# oracleasm createdisk ASMDISK4 /dev/sde1 Writing disk header: done Instantiating disk: done [root@12C ~]# oracleasm createdisk ASMDISK5 /dev/sdf1 Writing disk header: done Instantiating disk: done [root@12C ~]# oracleasm createdisk ASMDISK6 /dev/sdg1 Writing disk header: done Instantiating disk: done [root@12C ~]# oracleasm createdisk ASMDISK7 /dev/sdh1 Writing disk header: done Instantiating disk: done [root@12C ~]# oracleasm createdisk ASMDISK8 /dev/sdi1 Writing disk header: done Instantiating disk: done [root@12C ~]# oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks... [root@12C ~]# oracleasm listdisks ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5 ASMDISK6 ASMDISK7 ASMDISK8 至此ASM创建完毕，GI的安装待续。
