First thing to note here is that FLOGI is issued to log into a switch 
and not to an end-port. Next thing is that the logs you emailed show you 
are most probably in a "loop topology" and not in a Fabric topology. So, 
FLOGI messages are probably not relevant, unless you can confirm that 
LPe1150 is indeed connected to a FC switch.

Now, moving to the array side as a potential cause, disk arrays normally 
have setting associated with the front-side ports, which when not 
configured properly may cause issues with FC discovery (especially, when 
in loop topology). I certainly don't know if that is the case here, but 
I'd make sure to go thru the Dell MD36xx guide to ensure you have 
configured they array properly for loop topology. For example, some 
initiators won't "connect" with a array if the array port doesn't have 
Hard-addressing enabled when in loop topology.

One more thing (this is an obvious one, so sorry, if you have already 
done this one) -- I am assuming you have properly presented the disk 
LUNs in MD36xx to the LPe1105 port WWN. Right ?

Hope this helps,
Sunny
