有台DS400，双控制器。管理时要装management station 和ServerRaid 8.25或更低版本。A控制器因为拔插缓存卡修好了，B控制器是坏的。

现象：ping 192.168.70.123 不通,124通,但用serverRaid 8.25无法连
telnet 192.168.70.124 不上去.
代理程序192.168.70.124已关闭.ping 通.telnet 代理端口不通

A控制器无法ping通,开机过程中指示灯提示缓存未就绪控制器未就绪时ping得通7个包后又ping不通了,ping通的过程中管理软件也连不进去.过一会儿控制器已就绪灯亮.缓存灯一直提示未就绪.

B控制器开机后指示灯提示缓存未就绪控制器未就绪一直不变,ping得通但连不进去.telnet IP 上不去.

拔插控制器或者对调两个控制器结果一样. 后面把两个控制器的缓存卡都拔插一遍，然后A控制器单独启动，一切正常，原有数据还在。然后在把B控制器接上，telnet 192.168.70.123 可以上去。而两个控制器都插着起动机器就会跟上面描述的一样，都起不来。

结果：A控制器因为拔插缓存卡修好了，B控制器是坏的。
