详细说明

The Set-VHD cmdlet sets the ParentPath or PhysicalSectorSizeBytes properties of a virtual hard disk. The two properties must be set in separate operations.

示例

Example 1

This example sets the parent of the virtual hard disk associated with ParentCopy.vhd as the parent of the chained virtual hard disk associated with Child1.vhd, where the leaf of the virtual disk chain is the virtual hard disk associated with Child2.vhd. The operation is performed in online mode.

PS C:\> Set-VHD –Path Child1.vhd –ParentPath ParentCopy.vhd –LeafPath Child2.vhd

Example 2

This example sets the parent of the virtual hard disk associated with ParentCopy.vhd as the parent of the chained virtual hard disk associated with Child1.vhd. This operation cannot be performed when the virtual disk chain is attached.

PS C:\> Set-VHD –Path Child1.vhd –ParentPath ParentCopy.vhd

Example 3

This example sets the parent of Child1.vhd to point to parentcopywithnewid.vhd, even though parentcopywithnewid.vhd has a different ID than the original parent of child1.vhd. The operation is performed in offline mode. This mode should be used with extreme caution, and only when it is certain that the block contents of the new and old parents are exactly the same. Otherwise data loss can occur.

PS C:\> Set-VHD -Path Child1.vhd -parentpath parentcopywithnewid.vhd -IgnoreMismatchId

Example 4

This example sets the physical sector size of a VHDX to 512 bytes.

PS C:\> Set-VHD –Path c:\test.vhdx –PhysicalSectorSizeBytes 512
