I'm facing an issue where my firmware RAID 5 setup using an Intel C600/X79 series SATA RAID Controller isn't recognized correctly by Debian GNU/Linux 12 (Bookworm). Despite configuring RAID 5 in BIOS, Debian sees my six 4TB disks as separate entities (sda to sdf) rather than a single RAID unit.
lsblk output :

Motherboard: ASRock E3C226D2I, UEFI-[Legacy]: American Megatrends v: P3.30 date: 06/04/2015
CPU: Intel Xeon E3-1220L v3
RAID Controller: Intel C600/X79 series, using the ahci driver
Kernel: 6.1.0-18-amd64
Disks: 6x Seagate 4TB
I've looked into solutions, including mdadm, but it seems the ahci driver is being used instead of a specific RAID driver. I understand Debian wasn't explicitly listed among the supported OS by my motherboard, but I was hoping to find a way to make the hardware RAID recognized properly under Debian.
Any suggestions or similar experiences ?
Thank you in advance!
