获取相应的挂载点的物理磁盘驱动器与WMI查询？ [英] Get corresponding physical disk drives of mountpoints with WMI queries?
问题描述
有没有一种方法来检索的挂载点（其安装到文件系统，而不是安装一个驱动器号的卷）及其所属的物理磁盘驱动器（S）与WMI？
Is there a way to retrieve a connection between a mountpoint (a volume which is mounted into the file system instead of mounted to a drive letter) and its belonging physical disk drive(s) with WMI?
例如我有被安装到一个W2K8服务器上的卷的挂载点C：\Data\和挂载点被铺展在物理磁盘驱动器2，4，和5这已经得到了一个驱动器的服务器（服务器管理器的数据管理显示），但我不能找到一个办法让这个使用WMI就知道了。
For example I have got a volume mountpoint on a W2K8 server which is mounted to "C:\Data\" and the mountpoint is spreaded on the physical disk drives 2, 4, and 5 of the server (the Data Management of the Server Manager shows that) but I cannot find a way to get this to know by using WMI.
卷信可以使用WMI的类被连接Win32_DiskDrive - > Win32_DiskDriveToDiskPartition - > Win32_DiskPartition - > Win32_LogicalDiskToPartition - >的Win32_LogicalDisk - 但问题是，该卷安装点未在类的Win32_LogicalDisk列出的，它们只在Win32_Volume列出。我没有找到一个方法来连接Win32_Volume与类Win32_DiskDrive类 - ？有缺少一些连接类
Volumes which have got a drive letter can be connected with the WMI-Classes Win32_DiskDrive --> Win32_DiskDriveToDiskPartition --> Win32_DiskPartition --> Win32_LogicalDiskToPartition --> Win32_LogicalDisk – but the problem is, that volume mountpoints aren’t listed in the class Win32_LogicalDisk, they are only listed in Win32_Volume. And I did not find a way to connect the class Win32_Volume with the class Win32_DiskDrive – there are missing some linking classes.
有谁知道一个解决方案
推荐答案
我所知道的是使用Win32 API帮助的唯一途径。
The only way I know of is using the Win32 API to help.
您打开使用手柄到卷<一HREF =http://msdn.microsoft.com/en-us/library/aa394515%28VS.85%29.aspx相对=nofollow> Win32_Volume .DeviceID，略作修改。您可以使用格式打开句柄到卷：
You open a handle to the volume using Win32_Volume.DeviceID, modified slightly. You can open a handle to the volume using the format:
\\.\Volume{[GUID]}
您那么就需要出具的 IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS 检索的 VOLUME_DISK_EXTENTS 结构。这种结构将包含卷的物理磁盘ID列表
You then need to issue IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS on the open handle to retrieve a VOLUME_DISK_EXTENTS structure. This structure will contain a list of physical disk ids for the volume.
使用这些磁盘的ID可以在 Win32_DiskDrive 的.index获得匹配的磁盘。
Using these disk ids you can query WMI on Win32_DiskDrive.Index to get the matching disk.
