标题: 双机断开网络后的包切换问题 [打印本页] 作者: blacksabbather 时间: 2008-02-04 17:51 标题: 双机断开网络后的包切换问题 大家好！
我配了一个双节热备，上面跑oracle
由于是远程连上去的，所以做网络测试的时候使用交换机端口关闭的方式。
当我把Node A连接到交换机的端口“disable”之后，它会认为Node B “fail”了 Node B会被重启，而Node A虽然网络已断，但是什么都不会做
反过来，如果oracle包在Node B上运行 把Node B的端口disable后Node B会老老实实交出锁盘并重启，Node A会接管
下面是我disable Node A后syslog.log中的关键内容：
