故障现象： 网络中断，导致 节点2在最后一步运行root.sh失败
处理过程：在失败的节点上，清理节点集群相关配置信息，然后重新跑root.sh脚本。
步骤如下：
第一步：
[root@libmgr2 ~]# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -verbose -deconfig -force
Using configuration parameter file: /u01/app/11.2.0/grid/crs/install/crsconfig_params

第二步：节点2重新跑root.sh脚本
第三步：节点1确认集群状态，故障处理结束。
