Convert-VHD

Convert-VHD

Converts the format, version type, and block size of a virtual hard disk file.

Syntax

Parameter Set: Default
Convert-VHD [-Path] <String> [-DestinationPath] <String> [-AsJob] [-BlockSizeBytes <UInt32> ] [-CimSession <Microsoft.Management.Infrastructure.CimSession[]> ] [-ComputerName <String[]> ] [-Credential <System.Management.Automation.PSCredential[]> ] [-DeleteSource] [-ParentPath <String> ] [-Passthru] [-VHDType <VhdType> {Unknown | Fixed | Dynamic | Differencing} ] [-Confirm] [-WhatIf] [ <CommonParameters>]

Detaillierte Beschreibung

The Convert-VHD cmdlet converts a virtual hard disk file by copying the data from a source virtual hard disk file to a new virtual hard disk file of a specified format and version type. The format is determined by the file name extension of the specified files, either .vhdx or .vhd. Conversion is an offline operation; the virtual hard disk must not be attached when the operation is started.

Parameter

-AsJob

Runs the cmdlet as a background job.

-BlockSizeBytes<UInt32>

Specifies the block size, in bytes, of the virtual hard disk after conversion.

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

Das Cmdlet wird in einer Remotesitzung oder auf einem Remotecomputer ausgeführt. Geben Sie einen Computernamen oder ein Sitzungsobjekt ein, wie z. B. die Ausgabe eines New-CimSession oder Get-CimSession-Cmdlets. Der Standardwert ist die aktuelle Sitzung auf dem lokalen Computer.

-ComputerName<String[]>

Specifies one or more Hyper-V hosts on which the virtual hard disk is to be converted. 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.

-DeleteSource

Specifies that the source virtual hard disk is to be deleted after the conversion.

-DestinationPath<String>

Specifies the path to the converted virtual hard disk file.

-ParentPath<String>

Specifies the parent path for the destination-differencing virtual hard disk file.

-Passthru

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

-Path<String>

Specifies the path to the virtual hard disk file to be converted. If a file name or relative path is specified, the path of the converted hard disk path is calculated relative to the current working directory

-VHDType<VhdType>

Specifies the type of the converted virtual hard disk. Allowed values are Fixed, Dynamic, and Differencing. The default is determined by the type of source virtual hard disk.

-Confirm

Fordert Sie vor der Ausführung des Cmdlet zum Bestätigen auf.

-WhatIf

Zeit, was passieren würde, wenn das Cmdlet ausgeführt wird. Das Cmdlet wird nicht ausgeführt.

<CommonParameters>

Dieses Cmdlet unterstützt die allgemeinen Parameter: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer und -OutVariable. Weitere Informationen finden Sie unter about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Eingaben

Der Eingabetyp ist der Typ der Objekte, die Sie per Piping an das Cmdlet übergeben können.

Ausgaben

Der Ausgabetyp ist der Typ der Objekte, die vom Cmdlet ausgegeben werden.

Beispiele

Example 1

This example converts a source VHD to a destination VHDX. Because the format is determined by the file name extension and the default type is determined by the source virtual hard disk when no type is specified, the destination virtual hard disk will be a VHDX-format disk of the same type as the source virtual hard disk.

PS C:\> Convert-VHD –Path c:\test\testvhd.vhd –DestinationPath c:\test\testvhdx.vhdx

Example 2

This example converts a source differencing disk of VHDX format to a destination differencing disk of VHD format that is connected to an existing parent disk.

PS C:\> Convert-VHD –Path c:\test\child1vhdx.vhdx –DestinationPath c:\test\child1vhd.vhd –VHDType Differencing –ParentPath c:\test\parentvhd.vhd
