问题描述
一、设备型号：S9712
二、版本信息：v200r003c00spc500
三、组网：S9712---业务口集群----S9712
四、故障现象：配置集群命令前业务板卡注册正常，配置集群命令重启设备后业务板卡注册不上、进而导致集群不能组建成功

处理过程
1、核对客户的设备型号、版本是否满足通过业务口组建集群；是，满足；
2、核对客户配置，无问题；
3、根据客户提供的诊断信息The canbus node of LPU board[1/1] detects that CPU was reset.此告警多次出现，单板复位；怀疑是不是板卡存在问题；
4、将配置的集群信息删除、重启设备发现板卡正常注册、无异常；排查板卡问题；
5、再次仔细检查诊断信息发现系统文件的存储路径不在CF卡上而在Flash文件中，怀疑是否是此问题导致；

6、将系统文件移动到cfcard里进行测试，故障解决。
根因
由于系统文件S9700-V200R003C00SPC500.CC不在CF上而在Flash里面导致组建集群不成功。
