詳細描述

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

參數

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

在遠端工作階段或遠端電腦上執行 Cmdlet。輸入電腦名稱或工作階段物件，例如 New-CimSession 或 Get-CimSession Cmdlet 的輸出。預設為本機電腦上目前的工作階段。

-ComputerName<String[]>

Specifies one or more Hyper-V hosts on which the parent of a virtual hard disk in a differencing hard disk chain is to be set. 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.

-Force

強制執行命令，不要求使用者確認。

-IgnoreIdMismatch

Specifies that the check for identifier mismatch between the parent and child virtual hard disk is to be skipped.

-LeafPath<String>

Specifies the path to the virtual hard disk file of the virtual hard disk representing the leaf node of the virtual hard disk chain. Required when performing the operation in online mode.

-ParentPath<String>

Specifies the path to the parent disk of a differencing virtual hard disk. Can be performed regardless of whether the disk is online or offline.

-Passthru

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

-Path<String>

Specifies the path to the virtual hard disk file of the virtual hard disk drive whose parent in the virtual hard disk chain is to be set.

-PhysicalSectorSizeBytes<UInt32>

Specifies the physical sector size, in bytes. Valid values are 512 and 4096. This parameter is supported only on a VHDX-format disk that is not attached when the operation is initiated.

-ResetDiskIdentifier

Indicates that the cmdlet modifies the disk identifier of the virtual disk associated with the virtual hard disk file. The disk identifier is the SCSI Vital Product Data (VPD) Page 0x83h identifier associated with a disk. Use this parameter only for a VHDX-format disk.

範例

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
