准备环境：
Oracle 10g 联机文档、已经配置10g数据库软件的主机、oracleasm library rpm包、2块5GB硬盘
1、 查看本机磁盘信息
[root@shiyueasm~]# fdisk -l
Disk/dev/sda: 16.1 GB, 16106127360 bytes
255 heads,63 sectors/track, 1958 cylinders
Units =cylinders of 16065 * 512 = 8225280 bytes

Disk/dev/sdc: 5368 MB, 5368709120 bytes
255heads, 63 sectors/track, 652 cylinders
Units =cylinders of 16065 * 512 = 8225280 bytes
Disk/dev/sdc doesn't contain a valid partition table
Disk/dev/sdd: 5368 MB, 5368709120 bytes
255heads, 63 sectors/track, 652 cylinders
Units =cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdd doesn't contain a validpartition table
2、 对新添加的2块磁盘进行分区
[root@shiyueasm~]# fdisk /dev/sdc
Devicecontains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Buildinga new DOS disklabel. Changes will remain in memory only,
until youdecide to write them. After that, of course, the previous
contentwon't be recoverable.
Warning:invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command(m for help): n

3、 上传 oracle asmlibrary rpm包并对上传的包进行安装
[root@shiyueasmu01]# cd asm rpm for rhel4.0/
[root@shiyueasmasm rpm for rhel4.0]# ll
total 236
-rw-r--r-- 1 root root 129218 Apr 29 2010oracleasm-2.6.9-42.ELsmp-2.0.3-1.i686.rpm
-rw-r--r-- 1 root root 13105 Apr 29 2010oracleasmlib-2.0.4-1.el4.i386.rpm
-rw-r--r-- 1 root root 82542 Apr 29 2010oracleasm-support-2.1.3-1.el4.i386.rpm
[root@shiyueasmasm rpm for rhel4.0]# rpm -ivh *

3:oracleasmlib ########################################### [100%]
4、 配置ASM驱动
[root@shiyueasm~]# /etc/init.d/oracleasm configure
Configuringthe Oracle ASM library driver.
This willconfigure the on-boot properties of the Oracle ASM library
driver. The following questions will determinewhether the driver is
loaded onboot and what permissions it will have. The current values
will beshown in brackets ('[]'). Hitting without typing an
answerwill keep that current value. Ctrl-Cwill abort.
Defaultuser to own the driver interface []: oracle
Defaultgroup to own the driver interface []: oinstall
StartOracle ASM library driver on boot (y/n) [n]: y
Scan forOracle ASM disks on boot (y/n) [y]:
WritingOracle ASM library driver configuration: done
Initializingthe Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLibdisks: [ OK ]
5、 创建ASM磁盘组
[root@shiyueasm~]# /etc/init.d/oracleasm createdisk VOL01 '/dev/sdc1'
Markingdisk "VOL02" as an ASM disk: [ OK ]
[root@shiyueasm~]# /etc/init.d/oracleasm createdisk VOL02 '/dev/sdd1'
Marking disk "VOL01" as anASM disk: [ OK ]
6、 手动创建磁盘组参数文件
[oracle@shiyueasm~]$ cd $ORACLE_HOME/dbs
[oracle@shiyueasmdbs]$ ll
total 48
-rw-r--r-- 1 oracle oinstall 934 May 26 10:52 db.sql
-rw-rw---- 1 oracle oinstall 1544 May 26 10:32 hc_shiyue.dat
-rw-r----- 1 oracle oinstall 12920 May 3 2001initdw.ora
-rw-r----- 1 oracle oinstall 8385 Sep 11 1998 init.ora
-rw-r--r-- 1 oracle oinstall 996 May 26 10:31 initshiyue.ora
-rw-rw---- 1 oracle oinstall 24 May 26 10:52 lkSHIYUE
-rw-r----- 1 oracle oinstall 1536 May 26 10:32 orapwshiyue
[oracle@shiyueasm dbs]$ viinit+ASM.ora
asm_diskstring=''
background_dump_dest=/u01/admin/shiyueasm/bdump
core_dump_dest=/u01/admin/shiyueasm/cdump
user_dump_dest=/u01/admin/shiyueasm/udump
instance_type='asm'
large_pool_size=20m
remote_login_passwordfile='shared'
7、 创建相关目录
[oracle@shiyueasm~]$ mkdir -p /u01/admin/shiyueasm/bdump
[oracle@shiyueasm~]$ mkdir -p /u01/admin/shiyueasm/cdump
[oracle@shiyueasm ~]$ mkdir -p/u01/admin/shiyueasm/udump
8、 切换至ASM实例
[oracle@shiyueasm ~]$ export ORACLE_SID=+ASM
