是物理网卡有问题吗？或者是网络有问题吗？
处理的步骤是什么？谢谢
ping 192.2.1.10 有丢包

道可道非常道

我查了一下
在配置了IPMP的系统，原因是网络负载过大，ICMP包不能在指定的时间内返回，建议增加IPMP的缺省延时配置后重

启IPMP进程即可减少报错的次数。
可以修改/etc/default/mpathd 文件
将变量FAILURE_DETECTION_TIME 的值增加就行了

/mpathd 文件已经修改了，
如何重启IPMP进程

没有解决啊，就算调整到30000ms，也是会报错的啊
根源是什么，是网卡问题，还是网络问题

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。

配了路由，但主机无法ping通，会自己down掉
