No worries mate. I assume you’ve had that MacBook Pro hooked up to it at some stage. Can you hook it up again and see what happens?
I checked here with my server volumes and I can’t see any other way of making the system look for them at startup. There obviously is a way, but I’m just not sure what it is right now, sorry.
You might also want to open Console and look at the log while all this is going on. There may be something there that makes some sense.
