实验环境：
Red Hat Enterprise Linux Server release 5
ORALCE 10g 10.2.0.1

一、磁盘规划分区
我的实验机器上存在三块硬盘，sda，sdb，sdc。其中sda只用来安装了操作系统，以及应用软件;sdb划分分区，这块硬盘用来存放数据库系统文件system，sysaux等等;sdc这块硬盘划分相应的分区，这块硬盘主要用来存放业务数据。

使用fdisk命令划分分区,具体过程略，创建完所有分区以后，使用如下命令来查看：
# fdisk -l
Disk /dev/sda: 16.1 GB, 16106127360 bytes
255 heads, 63 sectors/track, 1958 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 1697 13631121 83 Linux
/dev/sda2 1698 1958 2096482+ 82 Linux swap / Solaris
Disk /dev/sdb: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 652 5237158+ 5 Extended
/dev/sdb5 1 13 104359+ 83 Linux
/dev/sdb6 14 26 104391 83 Linux
/dev/sdb7 27 39 104391 83 Linux
/dev/sdb8 40 52 104391 83 Linux
/dev/sdb9 53 59 56196 83 Linux
/dev/sdb10 60 182 987966 83 Linux
/dev/sdb11 183 305 987966 83 Linux
/dev/sdb12 306 428 987966 83 Linux
/dev/sdb13 429 652 1799248+ 83 Linux
Disk /dev/sdc: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdc1 1 652 5237158+ 5 Extended
/dev/sdc5 1 123 987934+ 83 Linux
/dev/sdc6 124 246 987966 83 Linux
/dev/sdc7 247 369 987966 83 Linux
/dev/sdc8 370 492 987966 83 Linux
/dev/sdc9 493 620 1028128+ 83 Linux
/dev/sdc10 621 652 257008+ 83 Linux

二、为裸设备建立映射关系
在root提示符下键入：
# raw -a
查询当前已经建立的raw设备名，目前为空，我们可以从第一个设备名用起，
在root提示符下键入：
raw /dev/raw/raw1 /dev/sdb5
raw /dev/raw/raw2 /dev/sdb6
raw /dev/raw/raw3 /dev/sdb7
raw /dev/raw/raw4 /dev/sdb8
raw /dev/raw/raw5 /dev/sdb9
raw /dev/raw/raw6 /dev/sdb10
raw /dev/raw/raw7 /dev/sdb11
raw /dev/raw/raw8 /dev/sdb12
raw /dev/raw/raw9 /dev/sdc5
raw /dev/raw/raw10 /dev/sdc6
raw /dev/raw/raw11 /dev/sdc7
raw /dev/raw/raw12 /dev/sdc8
raw /dev/raw/raw13 /dev/sdc9
raw /dev/raw/raw14 /dev/sdc10
至此，我们创建了14个raw设备名，用于交给Oracle直接管理，，查看一下已经创建的raw设备名的情况：

# raw -a
/dev/raw/raw1: bound to major 8, minor 21
/dev/raw/raw2: bound to major 8, minor 22
/dev/raw/raw3: bound to major 8, minor 23
/dev/raw/raw4: bound to major 8, minor 24
/dev/raw/raw5: bound to major 8, minor 25
/dev/raw/raw6: bound to major 8, minor 26
/dev/raw/raw7: bound to major 8, minor 27
/dev/raw/raw8: bound to major 8, minor 28
/dev/raw/raw9: bound to major 8, minor 37
/dev/raw/raw10: bound to major 8, minor 38
/dev/raw/raw11: bound to major 8, minor 39
/dev/raw/raw12: bound to major 8, minor 40
/dev/raw/raw13: bound to major 8, minor 41
/dev/raw/raw14: bound to major 8, minor 42

如果想删除一个raw设备名（例如/dev/raw/raw1），在root提示符下键入：
# raw /dev/raw/raw1 0 0
这样创建的裸设备在重启后会失效，需要修改系统文件。

修改系统的初始化文件，添加如下行到 /etc/rc.local 文件：
raw /dev/raw/raw1 /dev/sdb5
raw /dev/raw/raw2 /dev/sdb6
raw /dev/raw/raw3 /dev/sdb7
raw /dev/raw/raw4 /dev/sdb8
raw /dev/raw/raw5 /dev/sdb9
raw /dev/raw/raw6 /dev/sdb10
raw /dev/raw/raw7 /dev/sdb11
raw /dev/raw/raw8 /dev/sdb12
raw /dev/raw/raw9 /dev/sdc5
raw /dev/raw/raw10 /dev/sdc6
raw /dev/raw/raw11 /dev/sdc7
raw /dev/raw/raw12 /dev/sdc8
raw /dev/raw/raw13 /dev/sdc9
raw /dev/raw/raw14 /dev/sdc10
chmod 660 /dev/raw/raw1
chmod 660 /dev/raw/raw2
chmod 660 /dev/raw/raw3
chmod 660 /dev/raw/raw4
chmod 660 /dev/raw/raw5
chmod 660 /dev/raw/raw6
chmod 660 /dev/raw/raw7
chmod 660 /dev/raw/raw8
chmod 660 /dev/raw/raw9
chmod 660 /dev/raw/raw10
chmod 660 /dev/raw/raw11
chmod 660 /dev/raw/raw12
chmod 660 /dev/raw/raw13
chmod 660 /dev/raw/raw14
chown oracle.dba /dev/raw/raw1
chown oracle.dba /dev/raw/raw2
chown oracle.dba /dev/raw/raw3
chown oracle.dba /dev/raw/raw4
chown oracle.dba /dev/raw/raw5
chown oracle.dba /dev/raw/raw6
chown oracle.dba /dev/raw/raw7
chown oracle.dba /dev/raw/raw8
chown oracle.dba /dev/raw/raw9
chown oracle.dba /dev/raw/raw10
chown oracle.dba /dev/raw/raw11
chown oracle.dba /dev/raw/raw12
chown oracle.dba /dev/raw/raw13
chown oracle.dba /dev/raw/raw14
也可以修改etc/udev/rules.d/60-raw.rules文件，添加如下记录
ACTION=="add",KERNEL=="sdb5",RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add",KERNEL=="sdb6",RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add",KERNEL=="sdb7",RUN+="/bin/raw /dev/raw/raw3 %N"

ACTION=="add",KERNEL=="sdc10",RUN+="/bin/raw /dev/raw/raw14 %N"
KERNEL=="raw[1-9]", OWNER="oracle", GROUP="oinstall", MODE="640"
