楼主，问题是否解决？

看着象路径来回切换。

c6t0d1<-->c4t0d1 (pv = 0x0000000114c4a000)
c6t0d4<-->c4t0d4 (pv = 0x0000000114c9e000)
c6t0d3<-->c4t0d3 (pv = 0x0000000114c5e000)

1.楼主的盘有镜像
2.如果出现频繁，又不影响业务，可以尝试修改磁盘（物理卷）的“IO Timeout (Seconds) ”

具体是出错的磁盘属于哪个vg可以这么看：#ll /dev/*/group |grep 0x010000
这样可以看到vg的名字。3楼，卷组名不一定是vg01。

察看报错信息对应那几个盘可以用#ll /dev/dsk/* |grep 磁盘次设备号这样可以找到对应的盘符信息
                                             如:#ll /dev/dsk/* |grep 0x060300
                                             当然这不也可以用三楼的方法计算出来,不过我个人觉得计算有时可能
不太准确.
建议搂住按照2楼所说,检查下链路. 看下是什么应用在使用这个vg,看下syslog和event log 还有ioscan等输出.

主要是想把该帖子顶出来，请高手分析一下。
最近我的小机也出了类似告警，经分析是由于瞬间I/O高所致，如不频繁可以不做处理。0x060100指的是c6t0d1，0x060400指的是c6t0d4，应该都是vg01下面的盘，楼主可以看看这些盘上运行了什么东西。

以上信息仅作讨论，希望高手看到后给予分析一下，尤其是那些16进制数据的含义，多谢！

检查一下SCSI链路。
