HAIP地址被占用导致集群一个节点无法正常启动的处理过程
集群一个节点无法启动
1 查询故障节点的集群的启动状态
[grid@rac2 rac2]$ crsctl stat res -t -init

此时只是启动了构建集群所需要的底层资源 CSSD 没有启动。
2 个节点正常，第二个节点CSSD无法正常启动，通过查看[grid@rac2 cssd]$ tail -100f ocssd.log | more日志发现如下报错

这个报错之13号的报错，我是在15号上午重启启动这个节点的集群，此时ocssd.log根本没有记录任何东西，也就是此时集群根本没有启动到这里，应该是卡在底层某个地方了。
通过occd.log历史信息我们发现核心是没有网络心跳
3 测试私网连接，发现在两个节点私网地址互通没问题

4 再看下网络配置信息ifocnfig -a
发现节点1的网卡eth1上有HAIP地址，而第个节点的eth1上没有HAIP地址，这个就比较奇怪了，很可能第二个节点启动了HAIP网段的地址。
我们在第二个节点查看，发现eth3配置了.
节点1：
eth1:1 Link encap:Ethernet HWaddr 08:00:27:AF:CA:C2
inet addr:169.254.13.18 Bcast:169.254.255.255 Mask:255.255.0.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
节点2
eth1 Link encap:Ethernet HWaddr 08:00:27:5B:E4:92
inet addr:192.168.57.102 Bcast:192.168.57.255 Mask:255.255.255.0
inet6 addr: fe80::a00:27ff:fe5b:e492/64 Scope:Link

eth3 Link encap:Ethernet HWaddr 08:00:27:ED:7D:A2
inet addr:169.254.1.100 Bcast:169.254.255.255 Mask:255.255.0.0

RX bytes:10457605 (9.9 MiB) TX bytes:13433 (13.1 KiB)
此时，应该是第二个节点中HAIP网段的地址被使用到了导致问题发生，我们尝试删除该网卡配置（不明确是何时被修改而增加了这个网卡和地址），重启集群
5 删除第二个节点的网卡eth3配置，重启集群，问题解决。
