What firmware you have on the controller? Can you update to latest FW if it is not latest. You can downloads latest FW from below link [URL]  Can you also ensure BIOS and iDRAC is also on latest FW.  Can you try AC Power Cycle (Power Off the server, Remove the power cable from all PSU and insert back after 1 or 2 minutes) of the server and check the behavior.
