一个hp rp5400系列的小型机，查看syslog 并按照ems执行提示

报告这样错误：
Event Time..........: Tue Aug 30 15:05:30 2011
Severity............: CRITICAL
Monitor.............: disk_em
Event #.............: 100237
Summary:
   Disk at hardware path 0/0/1/1.2.0 : Media failure

Description of Error:

   The device was unsuccessful in reading or writing data for the current I/O
   request due to an error on the medium. The data could not be recovered.

Probable Cause / Recommended Action:

   Reformatting the medium may fix the problem.

   Alternatively, the medium in the device is flawed. If the medium is
   removable, replace the medium with a fresh one.

   Alternatively, if the medium is not removable, the device has experienced
   a hardware failure. Contact your HP support representative to have the
   device checked.

从提示看故障比较严重：
问题1. 但是用dd  vgdisplay  lvdisplay  ioscan 查看也没异常情况，很正常啊？

为什么出现这样的情况，请高手指点？？

问题2.另外这个机器系统自带4块磁盘请问2个磁盘状态分别代表什么意思？读写？？

问题3.故障磁盘所在逻辑卷的时候故障磁盘第一个等常亮，反而不报错反而不亮这个正常吗？

（mirrordisk做的镜像，正常时候应该同步闪烁的吧？）

dd if=/dev/vg00/rlvol4 of=/dev/null bs=1024
