I could be mistaken here or just confused :w00t:. Not sure how you have separate databases on NodeA and Node B IF this is an Active/Passive Cluster as both nodes should share the same databases and drives. You should have a Node A and Node B and then SQL Server A that ride on those nodes and fail back and forth between them like a pendulum as it fails back and forth(hopefully that makes sense). I have usually found that depending how far along you are in this set up..meaning production or still setting it up,its easier to completely rebuild the cluster than to make changes to the ini files (IMHO). I know my answer is not addressing the SSIS problem but the link that was sent also is very nice and compete about the SSIS in a cluster.
