Re: PowerEdge T320 iDrac physical disk status unknown

my suggestions: make sure that the Collect System Inventory on Restart is enabled in the Bios/idrac, the system should be powered on to show the current information. You could also try rebooting the idrac, SSH into the idrac IP, then run racadm racreset, Or shut down the system, pull the power cords for ~30 seconds, then boot up.
