此次实验是基于Red Hat Enterprise Linux 4系统的实验：

[root@www ~]# cat /proc/version 
Linux version 2.6.9-67.ELsmp (brewbuilder@ls20-bc1-14.build.redhat.com) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-8)) #1 SMP Wed Nov 7 13:58:04 EST 2007

Library and Tools

安装：

[root@www ~]# rpm -Uvh oracleasm-support-2.1.3-1.el4.i386.rpm

配置：

[root@www ~]# vi /etc/sysconfig/rawdevices 

[root@www ~]# cat /etc/sysconfig/rawdevices 
# This file and interface are deprecated.
# Applications needing raw device access should open regular
# block devices with O_DIRECT.
# raw device bindings
# format:  <rawdev> <major> <minor>
#          <rawdev> <blockdev>
# example: /dev/raw/raw1 /dev/sda1
#          /dev/raw/raw2 8 5
/dev/raw/raw1 /dev/sdd1
/dev/raw/raw2 /dev/sde1
/dev/raw/raw3 /dev/sdf1
/dev/raw/raw4 /dev/sdg1

[root@www ~]# /sbin/service rawdevices restart
Assigning devices: 
           /dev/raw/raw1  -->   /dev/sdd1
/dev/raw/raw1:	bound to major 8, minor 49
           /dev/raw/raw2  -->   /dev/sde1
/dev/raw/raw2:	bound to major 8, minor 65
           /dev/raw/raw3  -->   /dev/sdf1
/dev/raw/raw3:	bound to major 8, minor 81
           /dev/raw/raw4  -->   /dev/sdg1
/dev/raw/raw4:	bound to major 8, minor 97
done

[root@www ~]# chown oracle:oinstall /dev/raw/raw[1-4]
[root@www ~]# chmod 660 /dev/raw/raw[1-4]

修改 /etc/udev/permissions.d/50-udev.permissions。原始设备在引导时会
重新映射。默认情况下，在引导时原始设备的拥有者将更改为 root 用户。如果
拥有者不是 oracle 用户，则 ASM 在访问共享分区时会出现问题。在
/etc/udev/permissions.d/50-udev.permissions 中为原始行
“raw/*:root:disk:0660”添加注释，然后添加一个新行
“raw/*:oracle:dba:0660”。

[root@www ~]# vi /etc/udev/permissions.d/50-udev.permissions
# raw devices
ram*:root:disk:0660
#raw/*:root:disk:0660
raw/*:oracle:dba:0660

配置asm

[root@www db]# /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 <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]: 
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver:                     [FAILED
]

出现了错误怎么办呢，从哪里看错误日志呢？

[root@www log]# tail -f /var/log/messages
Oct 22 16:21:31 www modprobe: FATAL: Module oracleasm not found. 
Oct 22 16:21:31 www oracleasm: Unable failed

google 了一下 http://www.alidba.net/index.php/archives/113
 说是rpm包的小版本的原因。
