Question

我有一个脚本，该脚本可以将400 vms的非托管磁盘转换为托管磁盘。我们的azure基础架构的构建方式使命名约定几乎与虚拟机的名称匹配或相同，例如，如果我有一个名为E1PrAcepyRg的虚拟机，它驻留在E1PrAcepyRg资源组中，因此我使用以下语句来将RG的名称存储在如下所示的变量中：

$VmCode = Read-Host "Partner/VM Code" (Will give a name of the VM)

$Rg = Get-AzureRmResourceGroup | Where-Object {$_.ResourceGroupName -like "*$VmCode*"} (this will store the name of the resource group)

问题是当我尝试执行$ Rg时我什么都没得到，在此之后，当我运行for循环以停止RG中的所有vm时，我得到以下错误：

Stop-AzVM : Cannot validate argument on parameter 'ResourceGroupName'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.
At line:1 char:35
+ Stop-AzureRmVM -ResourceGroupName $Rg.ResourceGroupName -Name $Vm.Nam ...
+                                   ~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidData: (:) [Stop-AzVM], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.Azure.Commands.Compute.StopAzureVMCommand

整个脚本如下-

$Global:ErrorActionPreference = 'Stop'

$Rg = Get-AzureRmResourceGroup | Where {$_.ResourceGroupName -like "*$VmCode*"}

我不确定我在做什么错，有人可以帮助我吗？在此先感谢

很明显，该错误表明您的$ Rg为空。为解决该问题，请尝试下面的代码来获取VM资源。

Get-AzureRmVM -ResourceGroupName "ResourceGroup11" -Name "VirtualMachine07"

您将收到如下响应：

如果您使用的是Azure CLI，请使用以下命令，该命令也在注释中提到

$Rg = (Get-AzVM | Where-Object {$_.Name -match "$VmCode"}).ResourceGroupName

希望有帮助。
