配置

twonodes#/etc/rc.d/init.d/oracleasm configure –i

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 []: 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 ]

不可以執行對/dev/dm-*進行化分割槽,因為兩個node的dm-*的連線的裝置不一定相同.

chown grid:asmadmin /dev/dm*

oracleasm createdisk OCRVG /dev/dm-7

這樣的操作是不建議的.

使用fdisk進行分割槽，這裡就分一個區

#fdisk /dev/mapper/Ds8100_ocr_1

nàpà1…àw

#partprobe 同步磁碟資訊

#fdisk –l的輸出為：

Disk /dev/mapper/ds8100_1: 128.8 GB, 128849018880 bytes

。。。。。。

Device Boot Start End Blocks Id System

/dev/mapper/ds8100_ocr_1p1 1 15665 125829081 83 Linux

。。。。。。

檢查DEV目錄下有沒有磁碟分割槽裝置

#ls –lt /dev/mapper

……

建立oracleasm磁碟

#oracleasm create disk OCRVG /dev/mapper/Ds8100_ocr_1p1

#oracleasm listdisks

OCRVG

節點2：

#partprobe

#ls –lt /dev/mapper 檢查存在分割槽的裝置

brw-rw---- 1 root disk 253, 20 Aug 13 09:37 ds8100_ocr_1p1

#oracleasm scandisks

#oracleasm listdisks

OCRVG

使用了asmlib管理磁碟就不需要設定磁碟訪問的許可權

如果不使用asmlib(在redhat6中),則需要手工配置udev
