SCSI报错代码示例
Windows服务器上频繁出现event上来源为disk，ID为153的事件，并且影响到了数据库业务的正常运行。
点击该事件的详细信息，可以看到对应的SCSI读写请求及其状态。
上文scsi的译义如下：
- offset 29 SCSI Satus为00，译义为
SCSISTAT_GOOD，对应SCSI端口和驱动。 - offset 30 SRB Status为04，译义为
SRB_STATUS_ERROR，对应SCSI请求的数据块。 - offset 31 SCSI command为88，译义为
SCSIOP_READ16，对应SCSI命令的类型。
由此可见，操作系统在向磁盘2（\Device\MPIODisk2）的逻辑块地址ca190处发起读操作时，磁盘子系统返回了错误，但此时SCSI端口和驱动的状态是正常的。
