分区划分完成后，检查分区结果，两个节点分别做检查。 [root@rac1 ~]# fdisk -l

5、映射裸设备
映射裸设备，分别在两个节点上配置，在这里映射的是扩展分区，而不是主分区，主分区是用来做ASM磁盘组安装数据库的。 [root@rac1 ~]# vi /etc/sysconfig/rawdevices /dev/raw/raw1 /dev/sda5
15
/dev/raw/raw2 /dev/sda6 /dev/raw/raw3 /dev/sda7 修改权限
[root@rac1 ~]# vi /etc/udev/permissions.d/50-udev.permissions raw/*:oracle:oinstall:0660 启动并验证，两台机器
[root@rac1 ~]# /etc/init.d/rawdevices start Assigning devices:
/dev/raw/raw1 --> /dev/sda5 /dev/raw/raw1: bound to major 8, minor 5 /dev/raw/raw2 --> /dev/sda6 /dev/raw/raw2: bound to major 8, minor 6 /dev/raw/raw3 --> /dev/sda7 /dev/raw/raw3: bound to major 8, minor 7 done
在rac2节点上启动并验证
[root@rac2 ~]# /etc/init.d/rawdevices start Assigning devices:
/dev/raw/raw1 --> /dev/sda5 /dev/raw/raw1: bound to major 8, minor 5 /dev/raw/raw2 --> /dev/sda6 /dev/raw/raw2: bound to major 8, minor 6 /dev/raw/raw3 --> /dev/sda7 /dev/raw/raw3: bound to major 8, minor 7 done
6、安装ASM
按照顺序安装以下三个包，两个节点都要安装。
首先oracleasm是要和系统内核版本一致的，查看linux内核版本。 [root@rac1 ~]# uname -a
Linux rac12.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
软件包oracleasm的版本必须和内核版本一致： oracleasm-support-2.1.7-1.el5.x86_64.rpm oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm oracleasmlib-2.0.4-1.el5.x86_64.rpm 按顺序安装三个软件包
