我正在尝试自动扩展我的Azure数据库。我已经找到了一个powershell工作流脚本的一个单一的数据库，它的工作完美。我想知道是否可以自动扩展我的弹性池。我试着重写剧本，但失败了很多次。
下面是脚本：

workflow Set-AzureSqlDatabaseEdition 
{ 
    param 
    ( 
        # Name of the Azure SQL Database server (Ex: bzb98er9bp) 
        [parameter(Mandatory=$true)]  
        [string] $SqlServerName, 

        # Target Azure SQL Elastic Pool
        [parameter(Mandatory=$true)]  
        [string] $ElasticPoolName, 

        # Desired Azure SQL Elastic Pool edition {Basic, Standard, Premium} 
        [parameter(Mandatory=$true)]  
        [string] $Edition, 

        # Desired DTU 
        [parameter(Mandatory=$true)]  
        [string] $DTU, 

        # DatabaseDtuMin  
        [parameter(Mandatory=$true)]
        [string] $DatabaseDtuMin,

        # DatabaseDtuMax
        [parameter(Mandatory=$true)]
        [string] $DatabaseDtuMax,

        # Credentials for $SqlServerName stored as an Azure Automation credential asset 
        # When using in the Azure Automation UI, please enter the name of the credential asset for the "Credential" parameter 
        [parameter(Mandatory=$true)]  
        [PSCredential] $Credential 
    ) 

    inlinescript 
    { 
        Write-Output "Begin vertical scaling script..." 

        # Establish credentials for Azure SQL Database server  
        $Servercredential = new-object System.Management.Automation.PSCredential($Using:Credential.UserName, (($Using:Credential).GetNetworkCredential().Password | ConvertTo-SecureString -asPlainText -Force))  

        # Create connection context for Azure SQL Database server 
        $CTX = New-AzureSqlDatabaseServerContext -ManageUrl “https://$Using:SqlServerName.database.windows.net” -Credential $ServerCredential 

        # Get Azure Elastic Pool context 
        $EP = Get-AzureRmSqlElasticPool $CTX ElasticPoolName $Using:ElasticPoolName 

        # Specify the specific performance level for the target $DatabaseName 
        $DTU = Get-AzureRmSqlElasticPool $CTX ElasticPoolName $Using:DTU 

        # Set the new edition/performance level 
        Set-AzureRmSqlElasticPool $CTX ElasticPoolName $DTU –ServiceObjective $DTU –Edition $Using:Edition -Force 

        # Output final status message 
        Write-Output "Scaled the performance level of $Using:DatabaseName to $Using:Edition - $Using:PerfLevel" 
        Write-Output "Completed vertical scale" 
    } 
}

字符串
如果可能的话，我希望有人能给我指出一个正确的方向。
非常感谢！！！
