When I install RHEL8.x I cound’t discover my RAID Controller’s devices on Install Storage set-up optional.When I try to google find the resolutions I know a large number of storage controller device’s drivers has been removed from RHEL8,which means the Dell R710/R610 installed H700 RAID controller card won’t be supported RHEL 8.X natively.
