通过安装rac 10g for linxu redhat as 4与rac 10g for linxu redhat as 5发现配置裸设备有些不同
下面列出两种版本下的配置
1.linux redhat as 4
Edit the /etc/sysconfig/rawdevices file, adding the following lines. /dev/raw/raw1 /dev/sdb1/dev/raw/raw2 /dev/sdc1/dev/raw/raw3 /dev/sdd1/dev/raw/raw4 /dev/sde1/dev/raw/raw5 /dev/sdf1 chown oracle:oinstall /dev/raw/raw1chown oracle:oinstall /dev/raw/raw2chown oracle:oinstall /dev/raw/raw3chown oracle:oinstall /dev/raw/raw4chown oracle:oinstall /dev/raw/raw5chmod 600 /dev/raw/raw1chmod 600 /dev/raw/raw2chmod 600 /dev/raw/raw3chmod 600 /dev/raw/raw4chmod 600 /dev/raw/raw5 修改 /etc/udev/permissions.d/50-udev.permissions，[root@rac1 ~]# vi /etc/udev/permissions.d/50-udev.permissions# raw devicesram*:root:disk:0660#raw/*:root:disk:0660raw/*:oracle:dba:0660 机器启动时能自动加载给oracle用户使用。 2.linux redhat as 5因为rh5中取消了rawdevices服务，要使用裸设备的话，需要做以下配置。# vi /etc/udev/rules.d/60-raw.rules
添加以下部分的内容
ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"
# start_udev
Starting udev: [ OK ]
