[root@oradb1 ~]# fdisk /dev/sdc
The number of cylinders for this disk is set to 72815.
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)

16 使用root用户安装配置asmlib
--这里使用asm工具对设备进行持久化，当然也可以使用udev 的方式对设备进行持久化！
--双节点都要configure
[root@oradb1 pub]# /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.
