Unable to view and add nodes in the Manage Nodes page

Updated May 19, 2017


Nodes cannot be viewed or added in the Manage Nodes page after migrating the Orion server.

The following message is shown in the OrionWeb log:

2017-05-17 10:34:15,379 [33] (4) ERROR Orion_Nodes_Add_Default - (null) System.ServiceModel.FaultException`1[SolarWinds.Orion.Core.Common.CoreFaultContract]: ProvideFault failed, check fault information. (Fault Detail is equal to SolarWinds.Orion.Core.Common.CoreFaultContract(Unknown): System.ArgumentOutOfRangeException: Engine Id 1 does not exist


All Orion Platform versions


This issue occurs if the old Orion server is still in the Engines table of the database and the nodes are still using the old Engine ID after migration.


Note: Back up your database before performing the following steps.

Verify if the nodes are using the old Engine ID

  1. Go to All Programs > SolarWinds Orion > Advanced Features.
  2. Expand the SolarWinds database and locate the Engines table.
  3. Right-click the Engines table and select Query table.
  4. Take note of the Engine ID of the old and the new servers.
  5. Right-click the NodesData table and select Query table.
  6. Check the nodes if they are using the EngineID of the old server.

Delete the old server entry

  1. In the Database Manager, right-click the Engines table and select Query table.
  2. Select Enable table editing, right-click the old server’s row in the table and select Delete the selected row(s).

Change the Engine ID of the nodes

  1. Right-click the SolarWinds database in the Database Manager and select New Query.
  2. Run the following query:
    SELECT TOP 1000 * FROM [dbo].[AllEngines]
    Update [dbo].[NodesData] set engineid = 'NumberGoesHere'

    Example: Old EngineId = 1       New EngineId = 2

    Update [dbo].[AllEngines] set EngineId = 2
    Where EngineId =  1
    For NPM 12.x:
    Update [dbo].[NodesData] set engineid = NumberGoesHere

    Example: Old EngineId = 1       New EngineId = 2

    Update [dbo].[NodesData] set Engineid = 2
