rpm -ivh device-mapper-multipath-libs-0.4.9-72.el6.x86_64.rpm
rpm -ivh device-mapper-multipath-0.4.9-72.el6.x86_64.rpm

cp /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf /etc
编辑/etc/multipath.conf
注释掉默认打开的defaults（3行数据）
打开其他defaults
添加黑名单，将本地磁盘加入黑名单
blacklist {
#       wwid 26353900f02796769
#       devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
#       devnode "^hd[a-z]"
        devnode "^sd[a-b]"
}

运行：
modprobe dm-multipath
modprobe dm-round-robin

/etc/init.d/multipathd restart
service multipathd restart
multipath -v2

multipath -ll

3600601600bc0450079272985cc9de711
然后编辑/etc/multipath.conf
命名格式化共享磁盘

RAC：
multipaths{
     multipath{
      wwid   "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
      alias    "ocrvote1"
      path_grouping_policy    multibus
      }
     multipath{

添加权限：（目前权限为root disk ）

udev 绑定:
BPM:
cd /dev/mapper
for i in ls *; do
printf "%s %s\n" "$i" "$(udevadm info --query=all --name=/dev/mapper/$i |grep -i dm_uuid)"; done

vi /etc/udev/rules.d/99-oracle-asmdevices.rules
