    绑定裸设备

[root@localhost ~]# fdisk -l

Disk /dev/sda: 32.2 GB, 32212254720 bytes
255 heads, 63 sectors/track, 3916 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

    ②  在 /etc/sysconfig/rawdevices、添加：

/dev/raw/raw5    /dev/sda5
/dev/raw/raw6    /dev/sda6
/dev/raw/raw7    /dev/sda7
/dev/raw/raw8    /dev/sda8
/dev/raw/raw9    /dev/sda9
/dev/raw/raw10   /dev/sda10
/dev/raw/raw11   /dev/sda11
/dev/raw/raw12   /dev/sda12

    ③  在 /etc/rc.d/init.d/rawdevices的start处的assign_raw下、添加：

sleep 3
chown -R oracle:oinstall /dev/raw/

    ④  校验裸设备

[root@localhost init.d]# chkconfig rawdevices on
[root@localhost init.d]# partprobe
[root@localhost init.d]# service rawdevices restart
Assigning devices: 
           /dev/raw/raw5  -->   /dev/sda5
/dev/raw/raw5:  bound to major 8, minor 5
           /dev/raw/raw6  -->   /dev/sda6
/dev/raw/raw6:  bound to major 8, minor 6
           /dev/raw/raw7  -->   /dev/sda7
/dev/raw/raw7:  bound to major 8, minor 7
           /dev/raw/raw8  -->   /dev/sda8

           /dev/raw/raw9  -->   /dev/sda9
/dev/raw/raw9:  bound to major 8, minor 9
           /dev/raw/raw10  -->   /dev/sda10

           /dev/raw/raw11  -->   /dev/sda11
/dev/raw/raw11: bound to major 8, minor 11
           /dev/raw/raw12  -->   /dev/sda12
/dev/raw/raw12: bound to major 8, minor 12
done
[root@localhost init.d]# raw -qa
/dev/raw/raw5:  bound to major 8, minor 5
/dev/raw/raw6:  bound to major 8, minor 6
/dev/raw/raw7:  bound to major 8, minor 7

/dev/raw/raw9:  bound to major 8, minor 9
/dev/raw/raw10: bound to major 8, minor 10
/dev/raw/raw11: bound to major 8, minor 11
/dev/raw/raw12: bound to major 8, minor 12

    ⑤  增加权限

[root@localhost init.d]# cd /dev/raw/
[root@localhost raw]# ls -l
