Removes the managed instance of SQL Server from the SQL Server Utility.
# Get Ucp connection
$UcpServerInstanceName = "ComputerName\InstanceName";
$UtilityInstance = new-object –Type Microsoft.SqlServer.Management.Smo.Server $UcpServerInstanceName;
$UcpConnection = new-object -Type Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection $UtilityInstance.ConnectionContext.SqlConnectionObject;
$Utility = [Microsoft.SqlServer.Management.Utility.Utility]::Connect($UcpConnection);
# Now remove the ManagedInstance from the SQL Server Utility
$ServerInstanceName = "ComputerName\InstanceName";
$Instance = new-object -Type Microsoft.SqlServer.Management.Smo.Server $ServerInstanceName;
$InstanceConnection = new-object -Type Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection $Instance.ConnectionContext.SqlConnectionObject;
$ManagedInstance = $Utility.ManagedInstances[$ServerInstanceName];
$ManagedInstance.Remove($InstanceConnection);
Note that it is important to refer to the SQL Server instance name exactly as it is stored in SQL Server. On a case-sensitive instance of SQL Server, you must specify the instance name using the exact casing as returned by @@SERVERNAME. To get the instance name for the managed instance of SQL Server, run this query on the managed instance:
select @@SERVERNAME AS instance_name
At this point, the managed instance of SQL Server is fully removed from the UCP. It disappears from the list view the next time you refresh data for the SQL Server Utility. This state is identical to a user successfully going through the remove managed instance operation in the SSMS user interface.
