Use PowerShell to add a managed instance to a failover group
Applies to: Azure SQL Managed Instance
This PowerShell script example creates two managed instances, adds them to a failover group, and then tests failover from the primary managed instance to the secondary managed instance.
If you don't have an Azure trail subscription, create a trial subscription before you begin.
Note
This article uses the Azure Az PowerShell module, which is the recommended PowerShell module for interacting with Azure. To get started with the Az PowerShell module, see Install Azure PowerShell. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.
This tutorial requires Azure PowerShell 1.4.0 or later. If you need to upgrade, see Install Azure PowerShell module. You also need to run Connect-AzAccount -Environment AzureChinaCloud
to create a connection with Azure.

1. Get-AzSqlDatabaseInstanceFailoverGroup | Gets or lists SQL Managed Instance failover groups. |
2. Switch-AzSqlDatabaseInstanceFailoverGroup | Executes a failover of a SQL Managed Instance failover group. |
Verify the roles of each server
Use the Get-AzSqlDatabaseInstanceFailoverGroup command to confirm the roles of each server:
# Verify the current primary role
Get-AzSqlDatabaseInstanceFailoverGroup -ResourceGroupName $resourceGroupName `
-Location $location -Name $failoverGroupName
Fail over to the secondary server
Use the Switch-AzSqlDatabaseInstanceFailoverGroup to fail over to the secondary server.
# Failover the primary managed instance to the secondary role
Write-host "Failing primary over to the secondary location"
Get-AzSqlDatabaseInstanceFailoverGroup -ResourceGroupName $resourceGroupName `

# Verify the current primary role
Get-AzSqlDatabaseInstanceFailoverGroup -ResourceGroupName $resourceGroupName `
-Location $location -Name $failoverGroupName
Clean up deployment
Use the following command to remove the resource group and all resources associated with it. You'll need to remove the resource group twice. Removing the resource group the first time will remove the managed instance and virtual clusters but will then fail with the error message Remove-AzResourceGroup : Long running operation failed with status 'Conflict'
. Run the Remove-AzResourceGroup command a second time to remove any residual resources as well as the resource group.
Remove-AzResourceGroup -ResourceGroupName $resourceGroupName
Full script
The following snippet is the full script:
# Add SQL Managed Instance to a failover group
<#
Due to SQL Managed Instance deployment times, plan for a full day to complete the entire script.
You can monitor deployment progress in the activity log within the Azure portal.
For more information on deployment times, see https://docs.azure.cn/azure-sql/managed-instance/management-operations-overview.
Closing the session will result in an incomplete deployment. To continue progress, you will
need to determine what the random modifier is and manually replace the random variable with
the previously-assigned value.
