1. 新建LVM卷：

   #lvcreate -L 2048M-n lv_system oracledg

   #lvcreate -L 1024M-n lv_redo01 oracledg

   #lvcreate -L 1024M-n lv_redo02 oracledg

   # lvcreate -L 1024M -n lv_redo03 oracledg

   #lvcreate -L 2048M-n lv_tools01 oracledg

   #lvcreate -L 2048M-n lv_rbs oracledg

   #lvcreate -L 2048M-n lv_undotdbs01 oracledg

   #lvcreate -L 2048M-n lv_tmp01 oracledg

   #lvcreate -L 512M-n lv_users01 oracledg

   #lvcreate -L 2048M-n lv_index01 oracledg

   #lvcreate -L 256M-n lv_control01 oracledg

   #lvcreate -L 256M-n lv_control02 oracledg

   #lvcreate -L 256M-n lv_control03 oracledg

   #lvcreate -L 128M-n lv_spfile oracledg

   #lvcreate -L 1024M-n lv_xdb01 oracledg

   #lvcreate -L 1024M-n lv_drsys01oracledg

   #lvcreate -L 512M-n lv_example01 oracledg

   #lvcreate -L 2048M-n lv_oracledg01 oracledg

   #lvcreate -L 2048M-n lv_oracledg02 oracledg

   #lvcreate -L 2048M -n lv_oracledg03oracledg

   #lvcreate -L 2048M -n lv_oracledg04oracledg

   #lvcreate -L 2048M -n lv_oracledg05oracledg

   #lvcreate -L 2048M -n lv_oracledg06oracledg

   #lvcreate -L 2048M -n lv_oracledg07oracledg

2. 检查系统是否创建过裸设备

   #cd /dev/raw

   #ls -al

   #raw -qa      //检查裸设备是否被占用，没占用则无信息输出

   备注：如果已有裸设备在使用，则新建裸设备不可与现有的裸设备序列号冲突

3. 新建裸设备（我环境中没有创建过裸设备）：

   # mknod /dev/raw/raw1  c 162 1 

   # mknod /dev/raw/raw2  c 162 2 

   # mknod /dev/raw/raw3  c 162 3 

   # mknod /dev/raw/raw4  c 162 4 

   # mknod /dev/raw/raw5  c 162 5 

   # mknod /dev/raw/raw6  c 162 6 

   # mknod /dev/raw/raw7  c 162 7 

   # mknod /dev/raw/raw8  c 162 8 

   # mknod /dev/raw/raw9  c 162 9 

   # mknod /dev/raw/raw10 c 162 10

   # mknod /dev/raw/raw11 c 162 11

   # mknod /dev/raw/raw12 c 162 12

   # mknod /dev/raw/raw13 c 162 13

   # mknod /dev/raw/raw14 c 162 14

   # mknod /dev/raw/raw15 c 162 15

   # mknod /dev/raw/raw16 c 162 16

   # mknod /dev/raw/raw17 c 162 17

   # mknod /dev/raw/raw18 c 162 18

   # mknod /dev/raw/raw19 c 162 19

   # mknod /dev/raw/raw20 c 162 20

   # mknod /dev/raw/raw21 c 162 21

   # mknod /dev/raw/raw22 c 162 22

   # mknod /dev/raw/raw23 c 162 23

   # mknod /dev/raw/raw24 c 162 24

4. 修改裸设备文件节点属组（以数据库使用为例）

   # chown -R oracle:oinstall /dev/raw/raw1 
   

   # chown -R oracle:oinstall /dev/raw/raw2 

   # chown -R oracle:oinstall /dev/raw/raw3 

   # chown -R oracle:oinstall /dev/raw/raw4 

   # chown -R oracle:oinstall /dev/raw/raw5 

   # chown -R oracle:oinstall /dev/raw/raw6 

   # chown -R oracle:oinstall /dev/raw/raw7 

   # chown -R oracle:oinstall /dev/raw/raw8 

   # chown -R oracle:oinstall /dev/raw/raw9 

   # chown -R oracle:oinstall /dev/raw/raw10

   # chown -R oracle:oinstall /dev/raw/raw11

   # chown -R oracle:oinstall /dev/raw/raw12

   # chown -R oracle:oinstall /dev/raw/raw13

   # chown -R oracle:oinstall /dev/raw/raw14

   # chown -R oracle:oinstall /dev/raw/raw15

   # chown -R oracle:oinstall /dev/raw/raw16

   # chown -R oracle:oinstall /dev/raw/raw17

   # chown -R oracle:oinstall /dev/raw/raw18

   # chown -R oracle:oinstall /dev/raw/raw19

   # chown -R oracle:oinstall /dev/raw/raw20

   # chown -R oracle:oinstall /dev/raw/raw21

   # chown -R oracle:oinstall /dev/raw/raw22

   # chown -R oracle:oinstall /dev/raw/raw23

   # chown -R oracle:oinstall /dev/raw/raw24

5. 绑定逻辑卷和裸设备：

   # raw /dev/raw/raw1 /dev/oracledg/lv_system

   # raw /dev/raw/raw2 /dev/oracledg/lv_redo01

   # raw /dev/raw/raw3 /dev/oracledg/lv_redo02

   # raw /dev/raw/raw4 /dev/oracledg/lv_redo03

   # raw /dev/raw/raw5 /dev/oracledg/lv_tools01

   # raw /dev/raw/raw6 /dev/oracledg/lv_rbs

   # raw /dev/raw/raw7 /dev/oracledg/lv_undotdbs01

   # raw /dev/raw/raw8 /dev/oracledg/lv_tmp01

   # raw /dev/raw/raw9 /dev/oracledg/lv_users01

   # raw /dev/raw/raw10 /dev/oracledg/lv_index01

   # raw /dev/raw/raw11 /dev/oracledg/lv_control01

   # raw /dev/raw/raw12 /dev/oracledg/lv_control02

   # raw /dev/raw/raw13 /dev/oracledg/lv_control03

   # raw /dev/raw/raw14 /dev/oracledg/lv_spfile

   # raw /dev/raw/raw15 /dev/oracledg/lv_xdb01

   # raw /dev/raw/raw16 /dev/oracledg/lv_drsys01

   # raw /dev/raw/raw17 /dev/oracledg/lv_example01

   # raw /dev/raw/raw18 /dev/oracledg/lv_oracledg01

   # raw /dev/raw/raw19 /dev/oracledg/lv_oracledg02

   # raw /dev/raw/raw20 /dev/oracledg/lv_oracledg03

   # raw /dev/raw/raw21 /dev/oracledg/lv_oracledg04

   # raw /dev/raw/raw22 /dev/oracledg/lv_oracledg05

   # raw /dev/raw/raw23 /dev/oracledg/lv_oracledg06

   # raw /dev/raw/raw24 /dev/oracledg/lv_oracledg07
