1.安装ASMLib相关包
节点2用同样的步骤安装这三个rpm软件包，不再赘述。
2.配置ASMLib
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 [grid]:
Default group to own the driver interface [asmadmin]:
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
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks:
[ OK ]

--我这里环境有7块盘，ASMLib使用的盘需要分区，每块盘整个分一个区即可：
/etc/init.d/oracleasm createdisk OCR1 /dev/sdb1
/etc/init.d/oracleasm createdisk OCR2 /dev/sdc1
/etc/init.d/oracleasm createdisk OCR3 /dev/sdd1
/etc/init.d/oracleasm createdisk DATA1 /dev/sde1
/etc/init.d/oracleasm createdisk DATA2 /dev/sdf1
/etc/init.d/oracleasm createdisk DATA3 /dev/sdg1
/etc/init.d/oracleasm createdisk FRA1 /dev/sdh1

3.安装GI时选择ASM磁盘
diskstrings设置为ORCL:*，正常就可以看到类似下面这样的ASM盘：
