Subscription doesn't exists when using Set-AzureSubscription

Question

I am trying to run a powershell script against all VMs in an azure subscription. I used AzureRunAsConnection to connect to the service principal. Using Get-AzureVM gives an error that I haven't set the default Subscription. When I try to set it using Select-AzureSubscription I am given an error message stating the subscription doesn't exist. Here's what I am using in the runbook.

'''
$conn = Get-AutomationConnection -Name 'AzureRunAsConnection'
Add-AzureRmAccount -ServicePrincipal -TenantId $conn.TenantID -ApplicationID $conn.ApplicationID -CertificateThumbprint $conn.CertificateThumbprint
Select-AzureSubscription -SubscriptionName *********
'''

The exact error message is:

'''
Select-AzureSubscription : The subscription name ***** doesn't exist.
Parameter name: id
At line:3 char:1
+ Select-AzureSubscription -Current -SubscriptionName "******** ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : CloseError: (:) [Select-AzureSubscription], ArgumentException
    + FullyQualifiedErrorId : Microsoft.WindowsAzure.Commands.Profile.SelectAzureSubscriptionCommand
'''

What am I doing wrong to keep getting this error?

Answer 1

There are three generations of Azure powershell modules, "Azure", "AzureRM", and "AZ". Looks like you've got multiple installed. Try

Select-AzureRmSubscription

instead.

Answer 2

@david is right you are confusing the commands, Classic (Azure) vs AzureRM.

If the goal is to get VM in subscripts below are sample code for Calssic and AzureRM

Classic

$ConnectionAssetName = "AzureClassicRunAsConnection"
$connection = Get-AutomationConnection -Name $connectionAssetName        
$Conn = Get-AutomationConnection -Name $ConnectionAssetName
$CertificateAssetName = $Conn.CertificateAssetName
$AzureCert = Get-AutomationCertificate -Name $CertificateAssetName
Set-AzureSubscription -SubscriptionName $Conn.SubscriptionName -SubscriptionId $Conn.SubscriptionID -Certificate $AzureCert 
Select-AzureSubscription -SubscriptionId $Conn.SubscriptionID
Get-AzureVM

AzureRM

$connectionName = "AzureRunAsConnection"
$servicePrincipalConnection=Get-AutomationConnection -Name $connectionName         
Add-AzureRmAccount -ServicePrincipal -TenantId $servicePrincipalConnection.TenantId -ApplicationId $servicePrincipalConnection.ApplicationId -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint
Get-AzureRMVM

Also keep in mind that connections are tied to a subscription so for AzureRM you do not needed to select a subscription. If you want to select one (Select-AzureRmSubscription) it should be the same as the one in the connection properties.
