oracleasmilb方式做ASM

1.       安装rpm

创新互联公司于2013年开始，先为西山等服务建站，西山等地企业，进行企业商务咨询服务。为西山企业网站制作PC+手机+微官网三网同步一站式服务解决您的所有建站问题。

rpm -ivh kmod-oracleasm-2.0.6.rh2-2.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 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

  1. [root@rac1 ~]# fdisk /dev/sdb

  2.  

  3. 完成后我们通过fdisk -l查看一下

  4. [root@rac1 ~]# fdisk -l

  5.  

  6. [root@rac1 ~]# /usr/sbin/oracleasm configure -i

  7. Default user to own the driver interface []: grid

  8. Default group to own the driver interface []: asmadmin

  9. Start Oracle ASM library driver on boot (y/n) [n]: y

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

  11.  

  12. [root@rac1 ~]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb1

  13. [root@rac1 ~]# /etc/init.d/oracleasm createdisk VOL2 /dev/sdc1

  14. [root@rac1 ~]# /etc/init.d/oracleasm createdisk VOL3 /dev/sdd1

  15.  

  16. 以下操作在另一个节点上进行，RAC2上操作

  17. [root@rac2 ~]# oracleasm scandisks
