出现错误“不允许更改属性 'osDisk.name'。”使用 Azure Powershell 脚本

Question

我正在尝试将带有托管磁盘的现有 Azure VM 移动到现有可用性集中。但是，当我应用命令时：

New-AzureRmVM -ResourceGroupName $rg -Location $OriginalVM.Location -VM $NewVM -DisableBginfoExtension

我收到以下错误：

New-AzureRmVM：不允许更改属性“osDisk.name”。 错误代码：PropertyChangeNotAllowed 错误消息：不允许更改属性“osDisk.name”。 状态码：409 原因短语：冲突 操作ID：c179070b-e189-4025-84b0-87ba748f5844 在行：2 字符：5 + 新 AzureRmVM -ResourceGroupName $rg -Location $OriginalVM.Locati ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~ + CategoryInfo : CloseError: (:) [New-AzureRmVM], ComputeCloudException + FullyQualifiedErrorId : Microsoft.Azure.Commands.Compute.NewAzureVMCommand

在 Azure 中，一旦将磁盘附加到 VM，就无法更改磁盘的名称。 OS 磁盘将获取您在创建 VM 期间提供的 VM 名称。您可以参考this link 了解更多详情。

我进行了测试并重现了与您相同的错误。因为我用Set-AzureRmVMOSDisk 更改了操作系统磁盘名称。然后我删除了更改操作系统磁盘名称的cmdlet并成功。

您可以参考创建 vm 而无需更改 OS 磁盘名称，如下 cmdlet：

$VirtualMachine = Set-AzureRmVMOSDisk -VM $VirtualMachine -ManagedDiskId $disk.Id -CreateOption Attach -Windows 

我使用的整个 powershell cmdlet：

#Provide the subscription Id
$subscriptionId = 'xxxxxx-xxxx-xxxx-xxxx-xxxxxxxx'

$resourceGroupName ='yangsatest'

$diskName = 'VM1_OsDisk_1_xxxxxxxxxxxx'
$location = 'eastus'

$virtualNetworkName = 'yangsatest-vnet'
$virtualMachineName = 'VM2'

$virtualMachineSize = 'Standard_A1'
Select-AzureRmSubscription -SubscriptionId $SubscriptionId

$disk =  Get-AzureRmDisk -ResourceGroupName $resourceGroupName -DiskName $diskName

$VirtualMachine = New-AzureRmVMConfig -VMName $virtualMachineName -VMSize $virtualMachineSize -AvailabilitySetId /subscriptions/xxxxx-xxxxxx-xxx-xxxx8-xxxxxx/resourceGroups/yangsatest/providers/Microsoft.Compute/availabilitySets/Myset

#Use the Managed Disk Resource Id to attach it to the virtual machine. Please change the OS type to linux if OS disk has linux OS
$VirtualMachine = Set-AzureRmVMOSDisk -VM $VirtualMachine -ManagedDiskId $disk.Id -CreateOption Attach -Windows

$publicIp = New-AzureRmPublicIpAddress -Name ($VirtualMachineName.ToLower()+'_ip') -ResourceGroupName $resourceGroupName -Location $location -AllocationMethod Dynamic

$vnet = Get-AzureRmVirtualNetwork -Name $virtualNetworkName -ResourceGroupName $resourceGroupName

$nic = New-AzureRmNetworkInterface -Name ($VirtualMachineName.ToLower()+'_nic') -ResourceGroupName $resourceGroupName -Location $location -SubnetId $vnet.Subnets[0].Id -PublicIpAddressId $publicIp.Id

$VirtualMachine = Add-AzureRmVMNetworkInterface -VM $VirtualMachine -Id $nic.Id

#Create the virtual machine with Managed Disk
New-AzureRmVM -VM $VirtualMachine -ResourceGroupName $resourceGroupName -Location $location 

---------更新---------- 更新脚本以适应官方文档：更改托管 Windows VM 的可用性集(https://docs.microsoft.com/en-us/azure/virtual-machines/windows/change-availability-set)：

#set variables
    $rg = "demo-resource-group"

#Get VM Details
    $OriginalVM = get-azurermvm -ResourceGroupName $rg -Name $vmName

    #Output VM details to file
    "VM Name: " | Out-File -FilePath $outFile

    }

    #Create the basic configuration for the replacement VM

    Set-AzureRmVMOSDisk -VM $NewVM -ManagedDisk $OriginalVM.StorageProfile.OsDisk.ManagedDisk.Id   -CreateOption Attach -Windows

    #Add Data Disks
    foreach ($disk in $OriginalVM.StorageProfile.DataDisks ) { 
    Add-AzureRmVMDataDisk -VM $newVM -Name $disk.Name -ManagedDiskId $OriginalVM.StorageProfile.DataDisks.Id -Caching $disk.Caching -Lun $disk.Lun -CreateOption Attach -DiskSizeInGB $disk.DiskSizeGB
    }

    #Add NIC(s)
    foreach ($nic in $OriginalVM.NetworkProfile.NetworkInterfaces.Id) {
        Add-AzureRmVMNetworkInterface -VM $NewVM -Id $nic
    }


    #Create the VM
    New-AzureRmVM -ResourceGroupName $rg -Location $OriginalVM.Location -VM $NewVM -DisableBginfoExtension

对我来说，问题是我创建了一个托管磁盘（来自 Azure 门户），我选择了错误的操作系统导致我出现这种情况，我使用正确的操作系统重新创建了托管磁盘，然后部署工作正常。
