[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)

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
