1 修改虛拟機的所有節點的*.vmx配置檔案
[root@anrac rac1]# ls
rac1_1-flat.vmdk rac1_1.vmdk rac1-ad5ae35a.vswp rac1-flat.vmdk rac1.nvram rac1.vmdk rac1.vmsd <b> rac1.vmx </b> rac1.vmxf
添加
disk.locking = "false"
對節點rac2 重複同樣的操作!
2 對磁盤進行分區(根據各個的實際情況)
[root@rac1 asmlib_rpm]# fdisk -l
Disk /dev/sda: 107.3 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda2 14 13054 104751832+ 8e Linux LVM
Disk /dev/sdb: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders

Disk /dev/sde: 42.9 GB, 42949672960 bytes
[root@rac1 asmlib_rpm]#
[root@rac1 asmlib_rpm]# fdisk /dev/sdb
The number of cylinders for this disk is set to 5221.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Command (m for help): n

Partition number (1-4): 1
First cylinder (1-5221, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-5221, default 5221): 2610
Partition number (1-4): 2
First cylinder (2611-5221, default 2611):
Using default value 2611
Last cylinder or +size or +sizeM or +sizeK (2611-5221, default 5221):
Using default value 5221
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
[root@rac1 asmlib_rpm]# fdisk -l /dev/sdb
/dev/sdb1 1 2610 20964793+ 83 Linux
/dev/sdb2 2611 5221 20972857+ 83 Linux
依次對 剩下的/dev/sdc /dev/sdd /dev/sde 進行類似操作
然後使用oracleasm 工具建立asm磁盤,由于oracle 11.2 将asm 歸屬由grid使用者管理,如果你的是11R1 則繼續使用oracle
[root@rac1 asmlib_rpm]# /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 --由于oracle 11.2 将asm 歸屬由grid使用者管理,如果你的是11R1 則繼續使用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 ]
以上步驟也要在rac2 節點上重複操作!
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL101 /dev/sdb1
Marking disk "VOL101" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL102 /dev/sdb2
Marking disk "VOL102" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL103 /dev/sdc1
Marking disk "VOL103" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL104 /dev/sdc2
Marking disk "VOL104" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL201 /dev/sdd1
Marking disk "VOL201" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL202 /dev/sdd2
Marking disk "VOL202" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL203 /dev/sde1
Marking disk "VOL203" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm createdisk VOL204 /dev/sde2
Marking disk "VOL204" as an ASM disk: [ OK ]
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm scandisks
[root@rac1 asmlib_rpm]# /etc/init.d/oracleasm listdisks
VOL101
VOL102
VOL103
VOL104
VOL201
VOL202
VOL203
VOL204
在節點二上進行驗證:
[root@rac2 software]# /etc/init.d/oracleasm scandisks
[root@rac2 software]# /etc/init.d/oracleasm listdisks
[root@rac2 software]#
至此 oracle rac 安裝asm磁盤的工作完成!
