I'm not sure if this helps, but I am running FC3 on my machine with a 
QLA2200. I have a FC attached tape library which has 3 LUNs, and it 
scans them and they work fine.

Kernel is 2.6.12-1.1372_FC3smp and it always "just worked".

The only thing I would be curious is if the other two LUNs you have are 
sequential or if there is a gap. I've seen weird things happen when 
there are multiple LUNs on machines where there is a gap (like 0, 3, 6 
instead of 0, 1, 2)
