it's me again :( I've asked a question here a few minutes ago ( [HP B110i controller not seeing storage array. Any ideas?](https://serverfault.com/questions/346593/hp-b110i-controller-not-seeing-storage-array-any-ideas) )

Turns out I was wrong, and there IS a P411 controller built in, I verified by opening up the server. 

The problem has changed somewhat now. The server/BIOS is seeing the built in P410 and the onboard B110i (I get the 'Initializing' messages for both, and get the option to enter ORCA or CLI setup for the P410, but it's not seeing the P411. 

The manual claims the server would self-configure, and I couldn't find any further options in BIOS or elsewhere. 

Sorry for having to ask again, but any ideas how to activate the P411? I checked the status LEDs on the controller, and only the "Port 2 active" LED is on, steady light, irrespective of if there's a SAS cable connected and to which of the two ports, and the port light on the D2600 isn't lighting up. 

Any ideas?

P.S.: The SAS cables have a diamond on one connector and a circle on the other. Does this have any significance? I couldn't find any reference to this. I tried it both ways around, didn't make a difference.
