Proliant server, Drive Array controller failure

Hello there,

The server was working properly with 2 sas disks!After long time without power electricity..not even at the plug,it came up with a 1783-Slot 0 Drive Array Controller failure![Controller self-test failure]. Its a E200i

Do i need to setup somehow the slots with the disks?I guess that the power off thing has to do something with that..

PS:The Array controller has flashing lights on when the server power on..then no lights on!In the Bios i can see that is recognised

PS:Is there any simple way to recognise again the array or to setup it?

Thanks
