标题: ipmp 配置下出现奇怪问题
两台sun 服务器，v880 v890 做oracle rac ,
配置了 4块网卡,做ipmp 只有一块网卡出现如下故障,其他内网/外网络ping 都正常,

有没有相关的大虾遇到并解决过?

ps : 系统没有什么负载时候也如此,

从 v880-priv ping v890-priv 没有这个情况发生

有可能是网络的问题。

Oracle的官方诊断描述(http://docs.sun.com/app/docs/doc/816-0211/6m6nc66sm?a=view)：
Cannot meet requested failure detection time of time ms on (inet[6] interface_name) new failure detection is time ms.

The round trip time for ICMP probes is higher than the specified failure detection time. The network is probably congested or the probe targets are loaded. in.mpathd automatically increases the failure detection time to whatever it can achieve under these conditions.

Improved failure detection time time ms on (inet[6] interface_name).
The round trip time for ICMP probes has now decreased and in.mpathd has lowered the failure detection time correspondingly.

故障解释和处理办法：该报错是指，从报文发送到接收返回的时间比指定的检测时间要长。当时的网络很有可能存在堵塞的情况。在这种情况下，进程in.mpathd会自动增加故障检测时间。建议继续观察网络的通信情况，看看是否存在堵塞。

    你的问题最后如何解决的？

必须要配网关且接到交换机上就ok了

    能具体点吗？我们的oracle rac 私有网络是通过交换机连接的 不是网线直连
