oracle asmilb方式做ASM

1. 安装rpm

rpm -ivh kmod-oracleasm-2.0.6.rh1-2.el6.x86_64.rpm oracleasmlib-2.0.4-1.el6.x86_64.rpm oracleasm-support-2.1.8-1.el6.x86_64.rpm

安装cvuqdisk-1.0.9-1.rpm，位于安装文件解压后rpm目录下cvuqdisk-1.0.9-1.rpm

2. 配置asm

[root@rac1 ~]# /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 <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) [n]: y

Scan for Oracle ASM disks on boot (y/n) [y]: y

Writing Oracle ASM library driver configuration: done

Initializing the Oracle ASMLib driver: [ OK ]

Scanning the system for Oracle ASMLib disks: [ OK ]

3. 标记磁盘，只在一个节点执行

[root@rac1 ~]# /usr/sbin/oracleasm createdisk VOL1 /dev/mapper/mpathap1(/dev/sdb1)

[root@rac1 ~]# /usr/sbin/oracleasm listdisks

VOL1

4. 其他节点扫描磁盘

[root@rac2 oracle]# /usr/sbin/oracleasm scandisks

Reloading disk partitions: done

Cleaning any stale ASM disks...

Scanning system for ASM disks...

Instantiating disk "VOL1"

[root@rac2 oracle]# /usr/sbin/oracleasm listdisks

VOL1

5. MPIO特殊配置

如果使用了linux自带的mpio，所有节点需要如下修改：

编辑/etc/sysconfig/oracleasm

修改ORACLEASM_SCANORDER=""为ORACLEASM_SCANORDER="dm"

重启asm服务

[root@rac1 etc]# /etc/init.d/oracleasm restart

#####/etc/init.d/oracleasm deletedisk VOL1(学习用，安装过程不使用)

重新激活磁盘modprobe –r lpfc

Modprobe lpfc

格式化每个磁盘
