详细说明

The Resize-VHD cmdlet resizes a virtual hard disk. This cmdlet lets you shrink or expand the size of a virtual hard disk, but the shrink operation is allowed only on VHDX virtual hard disks. The shrink operation fails if it would shrink the virtual disk to less than its minimum size (available through the VHDX object’s MinimumSize property).

Resize-VHD is an offline operation; the virtual hard disk must not be attached when the operation is initiated.

参数

-AsJob

Runs the cmdlet as a background job.

-CimSession<Microsoft.Management.Infrastructure.CimSession[]>

在远程会话中或远程计算机上运行该 cmdlet。输入计算机名或会话对象，如 New-cimsession 或 Get-cimsession cmdlet 的输出。默认为本地计算机上的当前会话。

-ComputerName<String[]>

Specifies one or more Hyper-V hosts on which a virtual hard disk is to be resized. NetBIOS names, IP addresses, and fully qualified domain names are allowable. The default is the local computer. Use localhost or a dot (.) to specify the local computer explicitly.

-Credential<System.Management.Automation.PSCredential[]>

Specifies one or more user accounts that have permission to perform this action. The default is the current user.

-Passthru

Specifies that an object is to be passed through to the pipeline representing the virtual hard disk to be resized.

-Path<String[]>

Specifies the path to the virtual hard disk that is to be resized.

-SizeBytes<UInt64>

Specifies the size to which the virtual hard disk is to be resized.

-ToMinimumSize

Specifies that the virtual hard disk is to be resized to its minimum possible size.

-Confirm

在运行 cmdlet 前提示你进行确认。

-WhatIf

显示在 cmdlet 运行时将发生的情况。该 cmdlet 不运行。

<CommonParameters>

此 cmdlet 支持常见的参数：-Verbose、-Debug、-ErrorAction、-ErrorVariable、-OutBuffer 和 -OutVariable。有关详细信息，请参阅 TechNet 上的 about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216)。

输入类型是可以传送到 cmdlet 的对象的类型。

输出

输出类型是 cmdlet 发出的对象的类型。

示例

Example 1

Expands the VHDX to 1 terabyte (assuming that the previous size was less than the new size prior to the command).

PS C:\> Resize-VHD –Path c:\BaseVHD.vhd –SizeBytes 1TB

Example 2

Shrinks the VHDX to one terabyte (assuming that the virtual hard disk object associated with the file path has a MinimumSize less than or equal to 1TB).

PS C:\> Resize-VHD –Path c:\BaseVHDX.vhdx –SizeBytes 1TB

Example 3

Shrinks the VHDX to its minimum possible size.

PS C:\> Resize-VHD –Path c:\BaseVHDX.vhdx –ToMinimumSize
