Register your servers and assign permissions for Azure Stack HCI, version 23H2 deployment

Applies to: Azure Stack HCI, version 23H2

This article describes how to register your Azure Stack HCI servers and then set up the required permissions to deploy an Azure Stack HCI, version 23H2 cluster.

Prerequisites

Before you begin, make sure you've completed the following prerequisites:

• Satisfy the prerequisites and complete deployment checklist.

• Prepare your Active Directory environment.

• Install the Azure Stack HCI, version 23H2 operating system on each server.

• Register your subscription with the required resource providers (RPs). You can use either the Azure portal or the Azure PowerShell to register. You need to be an owner or contributor on your subscription to register the following resource RPs:

  • Microsoft.HybridCompute
  • Microsoft.GuestConfiguration
  • Microsoft.HybridConnectivity
  • Microsoft.AzureStackHCI

  Note

  The assumption is that the person registering the Azure subscription with the resource providers is a different person than the one who is registering the Azure Stack HCI servers with Arc.

• If you're registering the servers as Arc resources, make sure that you have the following permissions on the resource group where the servers were provisioned:

  • Azure Connected Machine Onboarding
  • Azure Connected Machine Resource Administrator

  To verify that you have these roles, follow these steps in the Azure portal:

  1. Go to the subscription that you use for the Azure Stack HCI deployment.
  2. Go to the resource group where you're planning to register the servers.
  3. In the left-pane, go to Access Control (IAM).
  4. In the right-pane, go the Role assignments. Verify that you have the Azure Connected Machine Onboarding and Azure Connected Machine Resource Administrator roles assigned.

• Check your Azure policies. Make sure that:

  • The Azure policies aren't blocking the installation of extensions.
  • The Azure policies aren't blocking the creation of certain resource types in a resource group.
  • The Azure policies aren't blocking the resource deployment in certain locations.

Register servers with Azure Arc

Important

Run these steps on every Azure Stack HCI server that you intend to cluster.

1. Install the Arc registration script from PSGallery. This step is only required if you're using an OS ISO that's older than 2408. For more information, see What's new in 2408.

   PowerShell

   #Register PSGallery as a trusted repo
   Register-PSRepository -Default -InstallationPolicy Trusted
   
   #Install required PowerShell modules in your node for registration
   Install-Module Az.Accounts -RequiredVersion 3.0.0
   Install-Module Az.Resources -RequiredVersion 6.12.0
   Install-Module Az.ConnectedMachine -RequiredVersion 0.8.0
   
   
   #Install Arc registration script from PSGallery 
   Install-Module AzsHCI.ARCinstaller
   

   Output

   Here's a sample output of the installation:

   PS C:\Users\SetupUser> Install-Module Az.Accounts -RequiredVersion 3.0.0
   PS C:\Users\SetupUser> Install-Module Az.Resources -RequiredVersion 6.12.0
   PS C:\Users\SetupUser> Install-Module Az.ConnectedMachine -RequiredVersion 0.8.0
   PS C:\Users\SetupUser> Install-Module -Name AzSHCI.ARCInstaller                                           
   NuGet provider is required to continue                                                                                  
   PowerShellGet requires NuGet provider version '2.8.5.201' or newer to interact with NuGet-based repositories. The NuGet  provider must be available in 'C:\Program Files\PackageManagement\ProviderAssemblies' or
   'C:\Users\SetupUser\AppData\Local\PackageManagement\ProviderAssemblies'. You can also install the NuGet provider by
   running 'Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force'. Do you want PowerShellGet to install
   and import the NuGet provider now?
   [Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"): Y
   PS C:\Users\SetupUser>
   

2. Set the parameters. The script takes in the following parameters:

   Parameters	Description
   SubscriptionID	The ID of the subscription used to register your servers with Azure Arc.
   TenantID	The tenant ID used to register your servers with Azure Arc. Go to your Microsoft Entra ID and copy the tenant ID property.
   ResourceGroup	The resource group precreated for Arc registration of the servers. A resource group is created if one doesn't exist.
   Region	The Azure region used for registration. See the Supported regions that can be used.
   AccountID	The user who registers and deploys the cluster.
   ProxyServer	Optional parameter. Proxy Server address when is required for outbound connectivity.
   DeviceCode	The device code displayed in the console at https://microsoft.com/devicelogin and is used to sign in to the device.

   PowerShell

   #Define the subscription where you want to register your server as Arc device
   $Subscription = "YourSubscriptionID"
   
   #Define the resource group where you want to register your server as Arc device
   $RG = "YourResourceGroupName"
   
   #Define the region you will use to register your server as Arc device
   $Region = "eastus"
   
   #Define the tenant you will use to register your server as Arc device
   $Tenant = "YourTenantID"
   
   #Define the proxy address if your HCI deployment access internet via proxy
   $ProxyServer = "http://proxyaddress:port"
   

   Output

   Here's a sample output of the parameters:

   PS C:\Users\SetupUser> $Subscription = "<Subscription ID>"
   PS C:\Users\SetupUser> $RG = "myashcirg"
   PS C:\Users\SetupUser> $Tenant = "<Tenant ID>"
   PS C:\Users\SetupUser> $Region = "eastus"
   PS C:\Users\SetupUser> $ProxyServer = "<http://proxyserver:tcpPort>"
   

3. Connect to your Azure account and set the subscription. You'll need to open browser on the client that you're using to connect to the server and open this page: https://microsoft.com/devicelogin and enter the provided code in the Azure CLI output to authenticate. Get the access token and account ID for the registration.

   PowerShell

   #Connect to your Azure account and Subscription
   Connect-AzAccount -SubscriptionId $Subscription -TenantId $Tenant -DeviceCode
   
   #Get the Access Token for the registration
   $ARMtoken = (Get-AzAccessToken).Token
   
   #Get the Account ID for the registration
   $id = (Get-AzContext).Account.Id   
   

   Output

   Here's a sample output of setting the subscription and authentication:

   PS C:\Users\SetupUser> Connect-AzAccount -SubscriptionId $Subscription -TenantId $Tenant -DeviceCode
   WARNING: To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code A44KHK5B5
   to authenticate.
   
   Account               SubscriptionName      TenantId                Environment
   -------               ----------------      --------                -----------
   guspinto@contoso.com AzureStackHCI_Content  <Tenant ID>             AzureCloud
   
   PS C:\Users\SetupUser> $ARMtoken = (Get-AzAccessToken).Token
   PS C:\Users\SetupUser> $id = (Get-AzContext).Account.Id
   

4. Finally run the Arc registration script. The script takes a few minutes to run.

   PowerShell

   #Invoke the registration script. Use a supported region.
   Invoke-AzStackHciArcInitialization -SubscriptionID $Subscription -ResourceGroup $RG -TenantID $Tenant -Region $Region -Cloud "AzureCloud" -ArmAccessToken $ARMtoken -AccountID $id -Proxy $ProxyServer
   

   If you're accessing the internet via a proxy server, you need to pass the -proxy parameter and provide the proxy server as http://<Proxy server FQDN or IP address>:Port when running the script.

   For a list of supported Azure regions, see Azure requirements.

   Output

   Here's a sample output of a successful registration of your servers:

   PS C:\Users\Administrator> Invoke-AzStackHciArcInitialization -SubscriptionID $Subscription -ResourceGroup $RG -TenantID $Tenant -Region $Region -Cloud "AzureCloud" -ArmAccessToken $ARMtoken -AccountID $id
   >>

   PS C:\Users\Administrator>
   

5. After the script completes successfully on all the servers, verify that:

   1. Your servers are registered with Arc. Go to the Azure portal and then go to the resource group associated with the registration. The servers appear within the specified resource group as Machine - Azure Arc type resources.

      

   2. The mandatory Azure Stack HCI extensions are installed on your servers. From the resource group, select the registered server. Go to the Extensions. The mandatory extensions show up in the right pane.

      

Assign required permissions for deployment

1. In the Azure portal, go to the subscription used to register the servers. In the left pane, select Access control (IAM). In the right pane, select + Add and from the dropdown list, select Add role assignment.

   

2. Go through the tabs and assign the following role permissions to the user who deploys the cluster:

   • Azure Stack HCI Administrator
   • Reader

3. In the Azure portal, go to the resource group used to register the servers on your subscription. In the left pane, select Access control (IAM). In the right pane, select + Add and from the dropdown list, select Add role assignment.

   

4. Go through the tabs and assign the following permissions to the user who deploys the cluster:

   • Key Vault Data Access Administrator: This permission is required to manage data plane permissions to the key vault used for deployment.
   • Key Vault Secrets Officer: This permission is required to read and write secrets in the key vault used for deployment.
   • Key Vault Contributor: This permission is required to create the key vault used for deployment.
   • Storage Account Contributor: This permission is required to create the storage account used for deployment.

5. In the right pane, go to Role assignments. Verify that the deployment user has all the configured roles.

6. In the Azure portal go to Microsoft Entra Roles and Administrators and assign the Cloud Application Administrator role permission at the Microsoft Entra tenant level.

   

   Note

   The Cloud Application Administrator permission is temporarily needed to create the service principal. After deployment, this permission can be removed.
