裝ASM和grid Infrastructure 12C

相關的資訊如下

首先是建立ASM磁碟組。

1、開啟虛擬機器新增SCSI控制器

2、增加磁碟，選擇建立新的虛擬盤

3、選擇磁碟檔案型別，我這裡選擇預設第一個即可

4、選擇固定大小磁碟

5、建立一塊2G的磁碟

6、重複2-5上面建立磁碟的步驟分別建立asmdisk1-asmdisk8的8塊磁碟，最終如下所示

9、啟動虛擬機器，使用root登入，首選需要安裝oracleasm-support 外掛，使用yum安裝。

yum install kmod-oracleasm

10、使用fdisk 建立分割槽，fdisk /dev/sbd 到i按照如下 建立8個磁碟主分割槽

[[email protected] ~]# fdisk /dev/sdi
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x311a383f.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-261, default 1): 
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-261, default 261): 
Using default value 261

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.
 

11、分割槽完畢後初始化相關oracleasm引數，使用root使用者執行oracleasm init

oracleasm init

12、配置oracleasm 的使用者為oracle 和組為oinstall

[[email protected] ~]# 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 <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) [y]:  
Scan for Oracle ASM disks on boot (y/n) [y]:
