RHEL 6.8 + Oracle 11g RAC multipath 配置
作者：互联网
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
