Oracle ASM 与 Oracle 数据库紧密集成在一起，并与 Oracle 的数据管理工具套件配合工作。它可以简化数据库存储管理，并提供原始磁盘 I/O 的性能。
配置 ASMLib。以 root 用户身份在两个节点上配置 ASMLib。
# /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
