oracle asmilb方式做ASM

1.        安裝rpm

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 

安裝cvuqdisk-1.0.9-1.rpm，位于安裝文件解壓后rpm目錄下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.        標記磁盤，只在一個節點執行

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

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

VOL1

4.        其他節點掃描磁盤

[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自帶的mpio，所有節點需要如下修改：

編輯/etc/sysconfig/oracleasm

修改ORACLEASM_SCANORDER=""為ORACLEASM_SCANORDER="dm"

重啟asm服務

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

#####/etc/init.d/oracleasm  deletedisk VOL1(學習用，安裝過程不使用)

重新激活磁盤modprobe –r lpfc   

             Modprobe lpfc

 格式化每個磁盤

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

2.  

3. 完成后我們通過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. 以下操作在另一個節點上進行，RAC2上操作

17. [root@rac2 ~]# oracleasm scandisks
