Smart Array B110i SATA RAID problem

[PeeX]

Sorry for my english, I'm using Google Translate

HP Proliant DL180 G6 with 2x Xeon 5650, 16 GB RAM and 8x HDD SATA ( 2 TB per HDD )

half a year ago we bought a server with 8 SATA HDD. Set up a RAID-controller. For six months it worked.

But yesterday I discovered that he had a flashing red LED

Windows does not respond to network requests
But BMC was available
Status was a critical
The monitoring sensors in front of "Module / Board" "IOH_NMI_DETECT" was the exclamation point.

status after the reboot was OK and there was no exclamation marks, it seems everything is working, but now can not see any HDD

I booted from the disk from the server and performed the diagnosis, but he says that everything is working fine and there are reports that no disks found
