I have 6.5 SP1b installed and I upgraded to SP2. The upgrade went fine but when the server starts back up it goes into a loop and keeps restarting.. I have loaded it with switches -na -ns -nl and it gets up to a certain point in Stage 0 and restarts. I put it into maintenance mode to load each nlm separately. When it get to cios.nlm is abends and re-starts. Has anyone seen this before? The server is a Dell 2850 PE.
