In Deployment Designer, orphaned shapes on the deployment diagram have a red dashed outline and the name of the shape appears in red. Orphaned shapes can occur when the logical datacenter diagram is modified or removed from the solution while the deployment diagram is closed.
If logical servers were removed from the logical datacenter diagram, those shapes appear orphaned when the deployment diagram is reopened.
To remove these orphaned shapes, synchronize the deployment diagram with the logical datacenter diagram. For more information, see How to: Synchronize Deployment Diagrams with Logical Datacenter Diagrams.
If the logical datacenter diagram was removed from the solution, all shapes on the deployment diagram appear orphaned.
To resolve this condition, add the missing logical datacenter diagram back to the solution.
