1.檢查內核版本

[root@vasm ~]# uname -a ?

Linux vasm 2.6.32-200.13.1.el5uek #1 SMP Wed Jul 27 21:02:33 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux ?

2.下載ASMLib驅動

http://www.oracle.com/technetwork/server-storage/linux/asmlib/index-101839.html?ssSourceSiteId=ocomen

3.安裝asmlib驅動

[root@vasm ~]# rpm -Uvh oracleasm-support-2.1.8-1.el5.x86_64.rpm oracleasmlib-2.0.4-1.el5.x86_64.rpm oracleasm-2.6.18-274.el5-2.0.5-1.el5.x86_64.rpm ?

warning: oracleasm-support-2.1.8-1.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159 ?

4.磁盤分區

[root@node1 ~]# fdisk /dev/sdb

Command (m for help): n

Command action

e extended

p primary partition (1-4)

p

Partition number (1-4): 1

First cylinder (1-102, default 1):

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-102, default 102):

Using default value 102

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

Syncing disks.

[root@node1 ~]# fdisk -l

/dev/sda1 ? ? ? ? ? 251 ? ? ? ?1958 ? ?13719510 ? 83 ?Linux

/dev/sda2 ? ? ? ? ? ? ? 1 ? ? ? ? 250 ? ? 2008093+ ?82 ?Linux swap / Solaris

5.配置ASMLIB

ASMLib configure command

[root@vasm ~]# /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 []: oracle ?

Default group to own the driver interface []: oinstall ?

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 ?]

[root@node1 linux-patch]# /etc/init.d/oracleasm scandisks

Scanning system for ASM disks: [ OK ]

6.檢查asm狀態

[root@vasm ~]# /etc/init.d/oracleasm status ?

Checking if ASM is loaded: yes ?

Checking if /dev/oracleasm is mounted: yes ?

7.創建共享磁盤

We have a set of 16 LUN’s ready, we will create 4 ASM disks on LUN’s sdb1,sdc1,sdd1 and sde1

[root@vasm ~]# /etc/init.d/oracleasm createdisk vol1 /dev/sdb1 ?

Marking disk "vol1" as an ASM disk: ? ? ? ? ? ? ? ? ? ? ? ?[ ?OK ?] ?

[root@vasm ~]# /etc/init.d/oracleasm createdisk vol2 /dev/sdc1 ?

Marking disk "vol2" as an ASM disk: ? ? ? ? ? ? ? ? ? ? ? ?[ ?OK ?] ?

[root@vasm ~]# /etc/init.d/oracleasm createdisk vol3 /dev/sdd1 ?

Marking disk "vol3" as an ASM disk: ? ? ? ? ? ? ? ? ? ? ? ?[ ?OK ?] ?

[root@vasm ~]# /etc/init.d/oracleasm createdisk vol4 /dev/sde1 ?

Marking disk "vol4" as an ASM disk: ? ? ? ? ? ? ? ? ? ? ? ?[ ?OK ?] ?

8.檢查磁盤狀態

[root@vasm ~]# /etc/init.d/oracleasm listdisks ?

VOL1 ?

VOL2 ?

VOL3 ?

VOL4 ?

root和oracle用戶運行都得到改結果，并且在rac2上運行也得到，說明配置成功。

補充：如果是10g的要配置裸設備，第四部結束后進行下面操作

在2個節點上做如下操作：

1.修改/etc/udev/rules.d/60-raw.rules 文件

添加如下內容：

ACTION=="add", KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="sdb2",RUN+="/bin/raw /dev/raw/raw2 %N"

ACTION=="add", KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw3 %N"

ACTION=="add", KERNEL=="sdc2",RUN+="/bin/raw /dev/raw/raw4 %N"

ACTION=="add", KERNEL=="sdc3",RUN+="/bin/raw /dev/raw/raw5 %N"

ACTION=="add",KERNEL=="raw[1-5]", OWNER="oracle", GROUP="oinstall", MODE="660"

2.重啟服務：

[root@rac1 ~]# start_udev

Starting udev: ? ? ? ? [ ?OK ?]

3.查看raw設備：

[root@rac1 ~]# ls -lrt /dev/raw

total 0

crw-rw---- 1 oracle oinstall 162, 5 Sep ?8 03:18 raw5

crw-rw---- 1 oracle oinstall 162, 4 Sep ?8 03:18 raw4

crw-rw---- 1 oracle oinstall 162, 1 Sep ?8 03:18 raw1

crw-rw---- 1 oracle oinstall 162, 3 Sep ?8 03:18 raw3

crw-rw---- 1 oracle oinstall 162, 2 Sep ?8 03:18 raw2
