系统事件中有错误提示，是什么原因？即结帖

服务器：双CPU 1.8G至强 + 1.5G内存 + SCSI 36G硬盘 + win2000系统

今天查看系统事件，发现有如下错误，请问是什么问题？有什么解决方法？

1、设备 \Device\Scsi\symmpi1 没有在传输等待时间内响应。
2、传呼期间在设备 \Device\Harddisk0\DR0 上检测到一个错误。

是不是硬盘有固障，希望解答，因为事关重大，谢谢！

操作系统在运行过程中会记录很多这样的事情，如果没有造成致命的错误，只是简单的记录，以供查看，像这样的记录应该算是正常的。不用担心

After much testing we discovered the root of our problem. It appears that a couple of Win2003 kernel i/o parameters that apply to the symmpi driver supplied from LSI where throttled to the max. The LSI driver installer sets these values to the max.

The parameters are located under:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Symmpi\Parameters\Device]

The first parameter is "MaximumSGList" which defines the maximum I/O block size. The symmpi driver supports block sizes of upto 1MB on 32bit Win2003. This was set to the maximum value by the installer.
The other parameter was the "NumberOfRequests" which defines the maximum number of concurrent I/Os (Guaranteed) by Win2003. Windows Server 2003 guarantees a maximum of 32 concurrent I/Os active on a
particular SCSI bus. This value was set to 255 by the LSI installer. Needless to say this value was much too high for our environment.

After a few tests we moderated both values respectively to 256KB and 100 concurrent I/Os. I am wandering whether we should have kept the block size at 1MB but that is bridge we can cross in the next tests.

正常得很啊

这种错误报告经常有，即使是新的盘。
