Hello,

I have a R740xd server running SQL server on it and has H740p Mini raid controller.
Few days ago, all disk volumes that are managed by raid controller has disapeared, and found PERC H740P Mini driver alert - yello mark - in device manager.

couldn't find any relevant logs from windows event view, so I tried to reboot the server but it didn't work.
After I deleted H740P Mini driver from device manager and reboot the server, it came back.

Driver version of H740p was 7.700.51.00 , firmware 50.3.0-1022
I already updated driver and firware to 7.705.13.0 , 50.5.0-2819_A06.1 as this version marked "urgent"

I was wondering what can be caused this problem so i can avoid same problem in the future.

thank you in advance.
