NAME
aacraid —
Adaptec AACRAID 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):
aacraid_load="YES"
DESCRIPTION
Theaacraid 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) 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 kernel is compiled with the
COMPAT_LINUX option, or the
aacraid_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.
HARDWARE
Controllers supported by the aacraid
driver include:
- 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.
