# aacraid(4)

Adaptec Series 6/7/8 6G and 12G SAS+SATA RAID controller driver

## NAME

**aacraid** – Adaptec Series 6/7/8 6G and 12G SAS+SATA RAID controller driver

## SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

**device** **pci** **device** **aacraid**

To compile in debugging code: **options** **AACRAID\_DEBUG=N**

Alternatively, to load the driver as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
aacraid_load="YES"
```

## DESCRIPTION

The **aacraid** driver provides support for the Adaptec by PMC RAID controllers, including Series 6/7/8 and upcoming families.

The RAID containers are handled via the **aacraidp0** bus. The physical buses are represented by the **aacraidp?** devices (beginning with aacraidp1). These devices enable the SCSI pass-passthrough interface and allows devices connected to the card such as CD-ROMs to be available via the CAM [scsi(4)](/scsi/4.md) subsystem. Note that not all cards allow this interface to be enabled.

The */dev/aacraid?* device nodes provide access to the management interface of the controller. One node exists per installed card. If the *aacraid\_linux.ko* and *linux.ko* modules are loaded, the Linux-compatible [ioctl(2)](/ioctl/2.md) interface for the management device will be enabled and will allow Linux-based management applications to control the card.

## HARDWARE

The **aacraid** driver supports the following Adaptec 6G and 12G SAS/SATA RAID controllers:

- Adaptec ASR-6405(T\|E)

- Adaptec ASR-6445

- Adaptec ASR-6805(T\|E\|Q\|TQ)

- Adaptec ASR-7085

- Adaptec ASR-7805(Q)

- Adaptec ASR-70165

- Adaptec ASR-71605(E\|Q)

- Adaptec ASR-71685

- Adaptec ASR-72405

- Adaptec Series 8 cards

## FILES

- */dev/aacraid?*

  aacraid management interface

## DIAGNOSTICS

Compiling with AACRAID\_DEBUG set to a number between 0 and 3 will enable increasingly verbose debug messages.

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.

## BUGS

The controller is not actually paused on suspend/resume.
