Oracle 11g RAC + RHEL 6.8 多路径配置如下，仅供参考。

<roidb1:+ASM1:/etc/udev/rules.d>$ls
    12-dm-permissions.rules      60-pcmcia.rules          90-alsa.rules              98-kexec.rules
    55-usm.rules                 60-raw.rules             90-hal.rules               99-fuse.rules
    60-fprint-autosuspend.rules  70-persistent-net.rules  97-bluetooth-serial.rules
    
    由于配置文件中使用了别名，所以这里也需要使用别名
