linux7.x:重启udev规则文件，使修改在内存生效
/sbin/udevadm control --reload-rules/sbin/udevadm trigger --type=devices --action=change

linux6.x:重启udev规则文件，使修改在内存生效

/sbin/udevadm control --reload-rules/sbin/start_udev

检查属主权限：

ll /dev/asm*ll /dev/*

linux7.x获取mpath多路径UUID方法：

cd /dev/mapperfor i in ls mpath*; doprintf "%s %s\n" "$i" "$(udevadm info --query=all --name=/dev/mapper/$i |grep -i dm_uuid)"; done
Oracle RAC用作ASM磁盘组的共享磁盘WWID必须一致
