IBM HA5.3主机宕机时，资源组无法自动切换问题【已解决】

有两台IBM的小型机运行了办公邮件系统，这两台服务器的HA版本为5.3，客户反映当两台主机gsoamail1（10.52.4.105）和gsoamail2（10.52.4.106）服务器都正常的时候切换资源组时可以正常切换，但当一台主机宕机时，另一台主机无法自动接管故障主机的资源组。

       检查主机发现以下问题，gsoamail1（10.52.4.105）的errpt存在如下报错，而gsoamail2（10.52.4.106）则没有。

1、请问串口心跳是否存在问题呢？

2、errpt中的报错是什么原因导致的，怎么可以排除？

3、假设串口心跳不通，走网络心跳，当两台主机都正常时，资源组可以切换，当一台主机宕机时，理论上资源组能否被另一个主机接管呢？

4、目前该问题可能的故障原因在哪里呢？
