在 Azure PowerShell Runbook 中更改 Azure Blob 存储层

Question

我发现有几篇文章使用ICloudBlob.SetStandardBlobTier("Archive") 来更改CloudBlockBlob 的层级。因此，我将以下我想在 Azure PowerShell Runbook 中运行的脚本放在一起。

Import-Module Azure

#Define storage account information
$StorageAccount = "xxxxx"
$StorageAccountKey = "xxxxx"
$containername = "xxxxx"

#Create a storage context
$context = New-AzureStorageContext -StorageAccountName $StorageAccount -StorageAccountKey $StorageAccountKey

# Get the blobs
$blobs = Get-AzureStorageBlob -Container $containername -Context $context
$blob = $blobs[0]

$blob.SetStandardBlobTier("Archive")

但这会产生以下错误消息

Method invocation failed because [Microsoft.WindowsAzure.Commands.Storage.Model.ResourceModel.AzureStorageBlob] does 
not contain a method named 'SetStandardBlobTier'.
At line:15 char:1
+ $blob.SetStandardBlobTier("Archive")
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : MethodNotFound

当我调用Write-Output $blobs[0].ICloudBlob | Get-Member 时，我的对象似乎真的没有这样的方法：

我什至不知道如何从对象中读取当前层。我浏览了属性和元数据，但没有运气。

我可以重现您的问题，您使用的命令是旧的，请按照步骤解决问题。

导航到您的 Runbook 所在的门户中的 automation account -> Modules -> 检查您是否有模块 Az.Accounts 1.6.2 和 Az.Storage 1.6.0，如果没有，请在 Browse Gallery 中搜索它们和Import（注意Az.Storage 1.6.0是Az.Storage的依赖，所以需要先导入Az.Accounts 1.6.2）。 如果您已经拥有旧版本，只需单击它们即可删除并导入上述最新版本。

然后在你的运行手册中，使用如下命令，它在我这边工作正常。

#Define storage account information
$StorageAccount = "xxxxx"
$StorageAccountKey = "xxxxx"
$containername = "xxxxx"

#Create a storage context
$context = New-AzStorageContext -StorageAccountName $StorageAccount -StorageAccountKey $StorageAccountKey

# Get the blobs
$blobs = Get-AzStorageBlob -Container $containername -Context $context
$blob = $blobs[0]

$blob.ICloudBlob.SetStandardBlobTier("Archive")
