27、HA配置到90%时失败，提示：Internal AAM Error-agent could not start
故障状态：
1、第一台主机加入到Cluster没问题，但是第二台主机加入到cluster时，走到90%出错，提示如下错误：Internal AAM Errors-agent could not start
复制代码
2、在aam_config_util_addnode.log文件里有类似如下错误信息：
01.01/23/10 16:20:49 [myexit ] Failure location:
02.01/23/10 16:20:49 [myexit ] function main::myexit called from line 2199
03.01/23/10 16:20:49 [myexit ] function main::start_agent called from line 1168
04.01/23/10 16:20:49 [myexit ] function main::add_aam_node called from line 171
05.01/23/10 16:20:49 [myexit ] VMwareresult=failure
故障分析：
这种故障一般和UDP 8043端口无法访问有一定关系；
解决方案：
确保UDP 8043端口畅通无阻，比如：
执行如下命令：
tcpdump -i vswif0 -s 900 -n udp port 8043 -w ${主机名}.pcap |
