.Nd Adaptec AACRAID Controller driver
|
|
|
|
|
.Sh SYNOPSIS
|
|
|
|
|
To compile this driver into the kernel,
|
|
|
|
|
place the following lines in your
|
|
|
|
|
kernel configuration file:
|
|
|
|
|
.Bd -ragged -offset indent
|
|
|
|
|
.Cd device pci
|
|
|
|
|
.Cd device aacraid
|
|
|
|
|
.Pp
|
|
|
|
|
To compile in debugging code:
|
|
|
|
|
.Cd options AACRAID_DEBUG=N
|
|
|
|
|
.Ed
|
|
|
|
|
.Pp
|
|
|
|
|
Alternatively, to load the driver as a
|
|
|
|
|
module at boot time, place the following line in
|
|
|
|
|
.Xr loader.conf 5 :
|
|
|
|
|
.Bd -literal -offset indent
|
|
|
|
|
aacraid_load="YES"
|
|
|
|
|
.Ed
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver provides support for the Adaptec by PMC RAID controllers,
|
|
|
|
|
including Series 6/7/8 and upcoming families.
|
|
|
|
|
.Pp
|
2013-05-28 09:33:46 +00:00
|
|
|
The RAID containers are handled via the
|
2013-05-24 09:22:43 +00:00
|
|
|
.Nm aacraidp0
|
|
|
|
|
bus.
|
2013-05-28 09:33:46 +00:00
|
|
|
The physical buses are represented by the
|
2013-05-24 09:22:43 +00:00
|
|
|
.Nm aacraidp?
|
|
|
|
|
devices (beginning with aacraidp1). These devices enable the
|
|
|
|
|
SCSI pass-thru interface and allows devices connected
|
|
|
|
|
to the card such as CD-ROMs to be available via the CAM
|
|
|
|
|
.Xr scsi 4
|
|
|
|
|
subsystem.
|
|
|
|
|
Note that not all cards allow this interface to be enabled.
|
|
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Pa /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
|
|
|
|
|
.Dv COMPAT_LINUX
|
|
|
|
|
option, or the
|
|
|
|
|
.Pa aacraid_linux.ko
|
|
|
|
|
and
|
|
|
|
|
.Pa linux.ko
|
|
|
|
|
modules are loaded, the
|
|
|
|
|
Linux-compatible
|
|
|
|
|
.Xr ioctl 2
|
|
|
|
|
interface for the management device will be enabled and will allow
|
|
|
|
|
Linux-based management applications to control the card.

|
|
|
Compiling with

|
|
|
.Dv AACRAID_DEBUG
|
|
|
|
|
set to a number between 0 and 3
|
|
|
|
|
will enable increasingly verbose debug messages.
|
|
|
|
|
.Pp
|
|
|
|
|
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.
