1 修改虚拟机的所有节点的*.vmx配置文件
[root@anrac rac1]# ls
rac1_1-flat.vmdk rac1_1.vmdk rac1-ad5ae35a.vswp rac1-flat.vmdk rac1.nvram rac1.vmdk rac1.vmsd rac1.vmx rac1.vmxf
添加
disk.locking = "false"
对节点rac2 重复同样的操作！
2 对磁盘进行分区(根据各个的实际情况)
[root@rac1 asmlib_rpm]# fdisk -l
Disk /dev/sda: 107.3 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders

Disk /dev/sdd: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
Disk /dev/sde: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
[root@rac1 asmlib_rpm]#
[root@rac1 asmlib_rpm]# fdisk /dev/sdb
The number of cylinders for this disk is set to 5221.
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)

[root@rac1 asmlib_rpm]#
[root@rac1 asmlib_rpm]#
[root@rac1 asmlib_rpm]# fdisk -l /dev/sdb
Disk /dev/sdb: 42.9 GB, 42949672960 bytes

/dev/sdb2 2611 5221 20972857+ 83 Linux
依次对 剩下的/dev/sdc /dev/sdd /dev/sde 进行类似操作
然后使用oracleasm 工具创建asm磁盘，由于oracle 11.2 将asm 归属由grid用户管理，如果你的是11R1 则继续使用oracle
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm configure
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 without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: grid --由于oracle 11.2 将asm 归属由grid用户管理，如果你的是11R1 则继续使用oracle
Default group to own the driver interface []: oinstall
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]
以上步骤也要在rac2 节点上重复操作！
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL101 /dev/sdb1
Marking disk "VOL101" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL102 /dev/sdb2
Marking disk "VOL102" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL103 /dev/sdc1
Marking disk "VOL103" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL104 /dev/sdc2
Marking disk "VOL104" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL201 /dev/sdd1
Marking disk "VOL201" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL202 /dev/sdd2
Marking disk "VOL202" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL203 /dev/sde1
Marking disk "VOL203" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL204 /dev/sde2
Marking disk "VOL204" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm scandisks
Scanning the system for Oracle ASMLib disks: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm listdisks
VOL101
VOL102
VOL103
VOL104
VOL201
VOL202
VOL203
VOL204
在节点二上进行验证：
[root@rac2 software]# /etc/init.d/oracleasm scandisks
Scanning the system for Oracle ASMLib disks: [ OK ]
[root@rac2 software]# /etc/init.d/oracleasm listdisks
VOL101
VOL102
VOL103
VOL104
VOL201
VOL202
VOL203
VOL204
[root@rac2 software]#
至此 oracle rac 安装asm磁盘的工作完成！
