How to install RHEL8(Centos) on Dell R710/R610 server

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.

Nevertheless you can still install RHEL8 on these machines with use of driver update disk(DUD).

Setup DUD

Using this link below ,you are specifically looking for the megaraid_sas drivers.

On my system, the DUD was /dev/sdb and the RHEL8 install media was /dev/sda.
