How Can I Obtain the Mapping Between Disk Partitions and Disk Devices on a Windows ECS?

This section uses an ECS running Windows Server 2008 R2 64bit as an example to describe how to obtain the mapping between disk partitions and disk devices.

1. Log in to the Windows ECS.
2. Click Start in the lower left corner of the desktop.
3. Choose Control Panel > Administrative Tools > Computer Management.
4. In the navigation pane on the left, choose Storage > Disk Management.

   1. Right-click the gray area where disk 1 is located, as shown in the red box in Figure 1.
   2. Click Properties.

      The SCSI Disk Device Properties dialog box is displayed, as shown in Figure 2.

   4. Record the digits following & in the parameter value, for example, 51776, which is the master and slave device number corresponding to the disk partition.
   5. Obtain the disk device according to the information listed in Table 1.
      The disk device corresponding to 51776 is xvde. The disk device used by disk 1 is xvde.
