I'm trying to use a 3ware 9550SX controller on CentOS 8. lspci shows the controller, but lsblk doesn't list the exported drives. I've exported 2 drives, each as single drives, no RAID mode being used.

Do I have a chance to use the drives? If so, how?

I can't change the hardware, so I grabbed a driver from elrepo.org. The following worked for me.

In Anaconda (the installer), enable networking then go to a terminal:

cd /run/install/repo
wget http://elrepo.reloumirrors.net/dud/el8/x86_64/dd-3w-sas-3.26.02.000-2.el8_1.elrepo.iso

You may have to select the specific driver for your hardware from the mirror.

Then reboot, and edit the grub config line by pressing Tab and add:

inst.dd=/dev/sda1

(or whatever the device is on your system). The installer should detect your disks then.

Support for that card was removed from RHEL 8 (the sources from which CentOS is built on).

Reference: Considerations in adopting RHEL 8: 11.1. Removed hardware support

This is also covered in the CentOS 8 Release Notes. Those notes mention that the CentOSPlus kernel contains these drivers, you can give that a shot. It also points to a 3rd-party repository that has driver update disks available for the removed devices.

Personally, I would strongly consider replacing it with a supported card at the earliest opportunity.

    Ok, thanks for the explanation, I think I will do so as suggested and get a newer card. The reason I came to this question was to re-actictivate an old server, but in this case, if I want an up-to-date os, I should get rid of the old obsolete stuff. – Michael Nov 10 '19 at 14:02
