ORACLE 配置ASM 用RULE 时的权限问题

moonstar00

ORACLE 配置ASM 用RULE 时会 编辑 60-raw.rules  

如::
ACTION=="add", KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdd1",RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sde1",RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="sdf1",RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="sdg1",RUN+="/bin/raw /dev/raw/raw6 %N"
KERNEL=="raw[1-2]", OWNER="root", GROUP="oinstall", MODE="0640"
KERNEL=="raw[3-6]", OWNER="oracle", GROUP="oinstall", MODE="0644"


这里面的 MODE 有 0640 , 0644 , 640 ,0660  这些有什么区别 各代表什么意思 . 这里OCR用的裸设备,和ASM 用的  用户组是否都必须为ORACLE 用户,还是一个是OCR 要用ROOT 用户 如示例中的设置
