一、环境描述
11g rac 双节点，AIX 小型机
二、现象
节点 2 无法启动
crsctl start crs 执行报错。
三、问题分析处理
1. 查看数据库日志

检查心跳网络，在节点一上 ping 节点二是通的，ping 自己当然也是通的。
这里感觉好奇怪，貌似心跳也没问题啊。各种问好？？？？？？整理下思路，在节点二上 ping 节点一，好嘛，真心 ping 不通。找到这个问题之后和客户沟通，发现网络刚刚做了调整导致的。经过网络工程师的处理。心跳网络恢复。轮到我上了，把集群给拉起来。

crsctl stop crs -- 报错
crsctl stop crs -f 强制关闭
crsctl start crs
