💖 AAC(4) — the Adaptec AdvancedRAID Controller driver, bestie edition 💖

Kernel Interfaces Manual ✨ okay so this is a kernel interfaces situation, we're deep in the guts of the system, and yes I'm gonna hold your hand through all of it 🫶

🌸 NAME 🌸

aac — the Adaptec AdvancedRAID Controller driver 💅

✨ SYNOPSIS ✨

Okay so you wanna compile this driver into the kernel? Bestie, say less. Drop these lines in your kernel configuration file:

device pci
device aac
device aacp

And if you want that debugging code in there too (messy but valid):

options AAC_DEBUG=N

OR, the lowkey easier route — load it as a module at boot time. Put this line in loader.conf(5):

aac_load="YES"

Slay. That's it. 🌈

🦋 DESCRIPTION 🦋

So the aac driver is out here providing support for the Adaptec AAC family of SCSI Ultra2, Ultra160, and Ultra320, SATA and SAS RAID controllers. Not me being obsessed with a RAID driver but here we are 💖

Access to RAID containers? Available via the /dev/aacd? device nodes. Easy.

The aacp device enables the SCSI pass-thru interface and lets devices connected to the card — like CD-ROMs — be available via the CAM scsi(4) subsystem. It's giving "your CD-ROM can hang with the cool kids now" energy 🎀

⚠️ Note that not all cards allow this interface to be enabled. So like, vibe check your hardware first, okay?

The /dev/aac? device nodes provide access to the management interface of the controller. One node exists per installed card. And the aliases /dev/afa? and /dev/hpn? exist for compatibility with the Dell and HP versions of management tools, respectively. (iykyk 💅)

AND — if the kernel is compiled with the COMPAT_LINUX option, or the aac_linux.ko and linux.ko modules are loaded, the Linux-compatible ioctl(2) interface for the management device will be enabled and will allow Linux-based management applications to control the card. Iconic crossover episode fr fr 😭

💀 DIAGNOSTICS 💀

Compiling with AAC_DEBUG set to a number between 0 and 3 will enable increasingly verbose debug messages. So like, 0 is chill, 3 is unhinged amounts of yapping 🙈

The adapter can send status and alert messages asynchronously to the driver. These messages are printed on the system console, and are also queued for retrieval by a management application. So nothing gets lost, she keeps receipts 💅

⭐ HISTORY ⭐

The aac driver first appeared in FreeBSD 4.3. Vintage. Retro. Nostalgic. She's been around 💖

Thank you for your service kings 🫡👑

😭 BUGS 😭

🚨 Bestie, listen. This driver is not compatible with Dell controllers that have version 1.x firmware. The firmware version is the same as the kernel version printed in the BIOS POST and driver attach messages. So check that before you come for her, okay?
⚠️ Also — the controller is not actually paused on suspend/resume. Not a vibe, but now you know fr fr.

And that's the whole page, bestie 💜 this one shipped as part of the Debian project, version dated July 10, 2009, and you can find it filed under AAC(4) ✨ mwah, go configure your RAID, you got this 🎀💅
