Hey I am trying to set up my new to me Dell R730XD server to move my existing unraid set up over to. Initially all of my installed drives were showing up in the BIOS. I got the raid controller set to HBA mode and managed to boot my Unraid server. 

This is where I ran into some issues. My drives are not showing up in Unraid, not even unassigned drives. I went back to the system config to check if the drives are still showing in bios. However, the option to see the PERC H730 controller is now gone so I cant see my drives. 

Any advice on what to do from here?
