额外注意：IB交换机也分可不可以管理，比如SX6036就是可以管理的IB交换机，
两台可以管理的IB交换机可以在IB交换机上配置高可用来实现其中一台IB交换机意外离线而导致的IB网络失效的问题。
若是不可管理的IB交换机，就只能在服务器端使用opensm来实现IB网络的高可用性。
介绍：
三台pcserver，安装RHEL7.2，每台pcserver上安装有两块HCA卡，每块HCA卡2个端口（port），
只不过每块HCA卡的第二个端口（port）没有插入IB线缆，并且每块HCA卡的第二个端口（port）在nmtui中被disable掉了。
三台主机的主机名为
rac1
rac2
node1
两台IB交换机，SX6036。
在三台pcserver上，安装mellanox的ofed驱动，ofed驱动使用opensmd服务来管理IB的子网。如下所示：
