1. Install 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

Install cvuqdisk-1.0.9-1.rpm, located in cvuqdisk-1.0.9-1.rpm in the rpm directory after the installation files have been unzipped.

two。 Configure 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 (yzone) [n]: y

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

Writing Oracle ASM library driver configuration: done

Initializing the Oracle ASMLib driver: [OK]

Scanning the system for Oracle ASMLib disks: [OK]

3. Mark the disk and execute on only one node

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

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

VOL1

4. Other nodes scan disk

[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. Special configuration of MPIO

If you use mpio that comes with linux, all nodes need to be modified as follows:

Edit / etc/sysconfig/oracleasm

Change ORACLEASM_SCANORDER= "" to ORACLEASM_SCANORDER= "dm"

Restart the asm service

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

# / etc/init.d/oracleasm deletedisk VOL1 (for learning, not for installation)

Reactivate disk modprobe-r lpfc

Modprobe lpfc

Format each disk

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

When it's done, let's check it through fdisk-l.

[root@rac1 ~] # fdisk-l

[root@rac1] # / usr/sbin/oracleasm configure-I

Default user to own the driver interface []: grid

Default group to own the driver interface []: asmadmin

Start Oracle ASM library driver on boot (yzone) [n]: y

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

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

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

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

The following operations are performed on another node, on RAC2

[root@rac2 ~] # oracleasm scandisks
