If you provide the device ID pairing [xxxx:yyyy] for the one that is not working, it will become clear. Can you show us the output from: lspci -nn Is it this one? Serial Attached SCSI controller [0107]: Intel Corporation C602 chipset 4-Port SATA Storage Control Unit [8086:1d6b] If so, the above device ID [8086:1d6b] is not supported in RHEL/CentOS 8, unfortunately.
