Kai*_*esh 5 c# windows ioctl iscsi
我正在尝试将缓冲区数据写入 SCSI 设备,但是当我触发 deviceIoControl 调用时,我收到 Windows 错误代码 183。错误代码指示文件已退出,但我无法理解与 IOCTL 调用相关的错误。
CreateFile 函数通过,因为我能够获得适当的设备句柄,如下所示。
int devHandle = DeviceIoControlHelper.CreateFile( deviceName, DeviceIoControlHelper.GENERIC_READ | DeviceIoControlHelper.GENERIC_WRITE, DeviceIoControlHelper.FILE_SHARE_READ | DeviceIoControlHelper.FILE_SHARE_WRITE, IntPtr.Zero, DeviceIoControlHelper.OPEN_EXISTING, Inttr.0Z
但是,当我尝试写入缓冲区时,出现错误:
dwReturned = 0;
int b = DeviceIoControlHelper.DeviceIoControl(
devHandle,
DeviceIoControlHelper.IOCTL_SCSI_PASS_THROUGH,
inpBuffer,
(uint)Marshal.SizeOf(info),
inpBuffer, //out pDriveLayout,
(uint)Marshal.SizeOf(info), //(uint)Marshal.SizeOf(typeof(DRIVE_LAYOUT_INFORMATION_EX)),
out dwReturned,
IntPtr.Zero);
Log.Write(Log.TraceLevel_5,"ExecuteDeviceIoControl return pass_through scsistatus = " + info.spt.ScsiStatus);
if (b == 0)
{
int win_err = this.GetWindowsErrorCode();
Log.Write(Log.TraceLevel_5, "ExecuteDeviceIoControl failed, error = " + win_err);
LogMyTrace.Write(LogMyTrace.TraceLevel_5, "ExecuteDeviceIoControl failed, error = " + win_err);
this.CloseOpenHandle(devHandle);
Marshal.FreeHGlobal(inpBuffer);
throw new Exception("DeviceIoControl failed " + deviceName +
" is '" + deviceName + "'. Windows Err is " + win_err);
}
The error code is 183.

请提供一些输入,说明导致此错误的原因和解决方案。
我使用的是 Windows 2008 R2 (x64),它是 iSCSI 路径。
