1.做raid 5

2.分区 fdisk /dev/sdc

3.创建裸设备并挂载：

Linux AS4:

将以下行添加到 /etc/sysconfig/rawdevices 中：

/etc/sysconfig/rawdevices

/dev/raw/raw1 /dev/sdc1
/dev/raw/raw2 /dev/sdd1
/dev/raw/raw3 /dev/sde1

要使映射立即生效，以 root 用户身份执行以下命令：
      # /sbin/service rawdevices restart
Assigning devices:
           /dev/raw/raw1  -->   /dev/sdc1
/dev/raw/raw1:  bound to major 8, minor 33
           /dev/raw/raw2  -->   /dev/sdd1
/dev/raw/raw2:  bound to major 8, minor 49
           /dev/raw/raw3  -->   /dev/sde1
/dev/raw/raw3:  bound to major 8, minor 65
done

# chown oracle:dba /dev/raw/raw[1-3]
# chmod 660 /dev/raw/raw[1-3]
# ls -lat /dev/raw/raw*
crw-rw----  1 oracle dba 162, 3 Nov  4 07:04 /dev/raw/raw3
crw-rw----  1 oracle dba 162, 2 Nov  4 07:04 /dev/raw/raw2
crw-rw----  1 oracle dba 162, 1 Nov  4 07:04 /dev/raw/raw1

以 oracle 用户身份执行

rac1-> ln -sf /dev/raw/raw1 /u01/oradata/devdb/asmdisk1 rac1-> ln -sf /dev/raw/raw2 /u01/oradata/devdb/asmdisk2 rac1-> ln -sf /dev/raw/raw3 /u01/oradata/devdb/asmdisk3

/etc/udev/permissions.d/50-udev.permissions

# raw devices ram*:root:disk:0660 #raw/*:root:disk:0660 raw/*:oracle:dba:0660

Linux AS5 ：

vi /etc/udev/rules.d/60-raw.rules
ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw3 %N"

cat /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
chown oracle:dba /dev/raw/raw1
