可以编辑 /etc/sysconfig/rawdevices ，使用 service rawdevices restart 命令完成裸设备的配置
1. 编辑后的 /etc/sysconfig/rawdevices 文件内容
# cat /etc/sysconfig/rawdevices
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdc1
/dev/raw/raw3 /dev/sdd1
/dev/raw/raw4 /dev/sde1
2. 启动裸设备服务 # service rawdevices restart
Assigning devices: /dev/raw/raw1 –> /dev/sdb1 /dev/raw/raw1: bound to major 8, minor 17
/dev/raw/raw2 –> /dev/sdc1 /dev/raw/raw2: bound to major 8, minor 33
/dev/raw/raw3 –> /dev/sdd1 /dev/raw/raw3: bound to major 8, minor 49
/dev/raw/raw4 –> /dev/sde1 /dev/raw/raw4: bound to major 8, minor 65 done
3. 最后的确认 # ls -l /dev/raw
crw-rw—- 1 root disk 162, 1 Jul 2 17:26 raw1
crw-rw—- 1 root disk 162, 2 Jul 2 17:26 raw2
crw-rw—- 1 root disk 162, 3 Jul 2 17:26 raw3
crw-rw—- 1 root disk 162, 4 Jul 2 17:26 raw4
使用编辑 /etc/udev/rules.d/60-raw.rules 文件，并使用 start_udev 命令完成裸设备对应关系的设定
1. 编辑后的 /etc/udev/rules.d/60-raw.rules文件内容
ACTION=="add",KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="17",RUN+="/bin/raw /dev/raw/raw1 %m"
ACTION=="add",KERNEL=="sdb2",RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="18",RUN+="/bin/raw /dev/raw/raw2 %m"
ACTION=="add",KERNEL=="sdb3",RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="19",RUN+="/bin/raw /dev/raw/raw3 %m"
ACTION=="add",KERNEL=="sdb4",RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="20",RUN+="/bin/raw /dev/raw/raw4 %m"
2.使用 start_udev 命令完成裸设备对应关系的设定
# start_udev
Starting udev: udevd[4578]: GOTO 'pulseaudio_check_usb' has no matching label in: '/lib/udev/rules.d/90-pulseaudio.rules'
[ OK ]
如果执行start_udev后没有在raw下没有生成相应的文件，重启数据库即可使之生效
3. 最后的确认 # ls -l /dev/raw
ls -l /dev/raw
