D2700 and P411 controller

[cnorton39]

I seem to have several threads on this issue, but I have yet to get an answer. 

I have one d2700 direct connected via SAS to a P411 controller inside a DL580 G8..  ORCA sees and attempts initialize the disks through the P411, but it doesn't detect the disks. Going through Post, my DL580 sees the controller, and I get message 289-Important. so the ACU sees the controller, but not the disks again.  I have updated the firmware, and changed the slot and cables, but still nothing.   

What am I missing?  

HP has no answers either.
