Recently, I discovered that Rocky Linux 9 has removed support for the HighPoint RocketRAID 2640X4SGL 4-Channel PCI-Express x4 SAS 3Gb/s RAID Controller and RocketRAID 2720A 8-Channel 6Gb/s SAS/SATA RAID Controller from the default Linux kernel. Unfortunately, the official drivers from HighPoint no longer compile on these newer distributions. Since my RAID card is still functioning perfectly, I saw no reason to replace it just because of
missing drivers. If you’re in the same situation, here’s how you can get your controller working again:

Visit the following URLs:

• RHEL 9

Find your OS version:

cat /etc/redhat-release

Download the dd-mvsas.iso for your version:

#For Rocky Linux 9.7:
wget https://elrepo.org/linux/dud/el9/x86_64/dd-mvsas-0.8.16-10.el9_7.elrepo.iso

Once you’ve downloaded the ISO file, mount it and install the RPM package inside:

# Mount the ISO
sudo mount dd-mvsas-0.8.16-10.el9_7.elrepo.iso /mnt/

# Navigate to the RPM directory
cd /mnt/rpms/x86_64

# Install the driver package
sudo rpm -i kmod-mvsas-0.8.16-10.el9_7.elrepo.x86_64.rpm

# Reboot your system
sudo reboot

That’s it! Your HighPoint RocketRAID 2640X4SGL / 2720A controller should now be recognized and working as expected. I hope this helps anyone facing the same issue. Let me know if you have any questions or run into any issues!
