使用 PowerShell 在相同或不同订阅的存储帐户中从 VHD 文件创建托管磁盘

此脚本在相同或不同订阅的存储帐户中从 VHD 文件创建托管磁盘。 使用此脚本将专用（未经过通用化/sysprep 处理）的 VHD 导入到托管 OS 磁盘以创建虚拟机。 同时，使用它将数据 VHD 导入到托管数据磁盘。

请勿在短时间内从一个 VHD 文件创建多个相同的托管磁盘。 若要从 VHD 文件创建托管磁盘，需创建该 VHD 文件的 blob 快照，然后再使用快照创建托管磁盘。 一分钟内只可创建一个 blob 快照，此限制会导致磁盘创建失败。 若要避免此限制，请从 VHD 文件创建托管快照，然后使用托管快照在短时间内创建多个托管磁盘。

如果没有 Azure 订阅，可在开始前创建一个试用帐户。

示例脚本

.DESCRIPTION

This sample demonstrates how to create a Managed Disk from a VHD file. 
Create Managed Disks from VHD files in following scenarios:
1. Create a Managed OS Disk from a specialized VHD file. A specialized VHD is a copy of VHD from an exisitng VM that maintains the user accounts, applications and other state data from your original VM. 
   Attach this Managed Disk as OS disk to create a new virtual machine.
2. Create a Managed data Disk from a VHD file. Attach the Managed Disk to an existing VM or attach it as data disk to create a new virtual machine.

.NOTES

1. Before you use this sample, please install the latest version of Azure PowerShell from here: http://go.microsoft.com/?linkid=9811175&clcid=0x409
2. Provide the appropriate values for each variable. Note: The angled brackets should not be included in the values you provide.


#>

#Provide the subscription Id
$subscriptionId = 'yourSubscriptionId'

#Provide the name of your resource group
$resourceGroupName ='yourResourceGroupName'

#Provide the name of the Managed Disk
$diskName = 'yourDiskName'

#Provide the size of the disks in GB. It should be greater than the VHD file size.
$diskSize = '128'

#Provide the URI of the VHD file that will be used to create Managed Disk. 
# VHD file can be deleted as soon as Managed Disk is created.
# e.g. https://contosostorageaccount1.blob.core.chinacloudapi.cn/vhds/contoso-um-vm120170302230408.vhd 
$vhdUri = 'https://contosoststorageaccount1.blob.core.chinacloudapi.cn/vhds/contosovhd123.vhd' 

#Provide the resource Id of the storage account where VHD file is stored.
#e.g. /subscriptions/6472s1g8-h217-446b-b509-314e17e1efb0/resourceGroups/MDDemo/providers/Microsoft.Storage/storageAccounts/contosostorageaccount
$storageAccountId = '/subscriptions/yourSubscriptionId/resourceGroups/yourResourceGroupName/providers/Microsoft.Storage/storageAccounts/yourStorageAccountName'

#Provide the storage type for the Managed Disk. PremiumLRS or StandardLRS.
$sku = 'Premium_LRS'

#Provide the Azure location (e.g. chinanorth) where Managed Disk will be located. 
#The location should be same as the location of the storage account where VHD file is stored.
#Get all the Azure location using command below:
#Get-AzureRmLocation
$location = 'chinanorth'

#Set the context to the subscription Id where Managed Disk will be created
Set-AzContext -Subscription $subscriptionId

#If you're creating an OS disk, add the following lines
#Acceptable values are either Windows or Linux
#$OSType = 'yourOSType'
#Acceptable values are either V1 or V2
#$HyperVGeneration = 'yourHyperVGen'

#If you're creating an OS disk, add -HyperVGeneration and -OSType parameters
$diskConfig = New-AzDiskConfig -SkuName $sku -Location $location -DiskSizeGB $diskSize -SourceUri $vhdUri -CreateOption Import

#Create Managed disk
New-AzDisk -DiskName $diskName -Disk $diskConfig -ResourceGroupName $resourceGroupName -StorageAccountId $storageAccountId

脚本说明

此脚本使用以下命令在不同订阅中从 VHD 创建托管磁盘。 表中的每条命令均链接到特定于命令的文档。

后续步骤

通过将托管磁盘附加为 OS 磁盘来创建虚拟机
