请教一个heartbeat的问题

请教一个heartbeat的问题
本人的集群有四部服务器，两部是真实服务器，另两部是均衡负载器load balancer，而均衡负载是使用active/slave模式，四部服务器都只是经网络线直接连至switch，两部均衡负载器load balancer未有以serial port 或网络线相互连接。

问题发生在均衡负载器(LB)身上，首先heartbeat程序已经在两部LB激活及运行(附件主(LB)log)，所有外来请求都会由主[webserver2.hostname](LB)接收，发到真实服务器，而次[temp1.localdomain](LB)则备用(附件次(LB)log)。
问题1
我尝试重新激活 主(LB) ---- 直接执行shutdown now r ，在重新激活开始直至激活完成后，次(LB)完全没有接管主均衡负载器的功能，接收外来请求，最后需要重新激活次(LB)的heartbeat>>> /etc/init.d/heartbeat stop>>>>
heartbeat /etc/init.d/heartbeat start
次(LB)才能开始主均衡负载器的功能，请问错误出自哪里?

根据HA文件的要求 除了网络联机 还需要一条RJ45 to DB9的crossover cable经switch 将主负载器及次负载器连接，请问可否直接用DB9 to DB9 的serial cable 将两部主机连接? 达到ha 的功能?
