.Sh NAME
.Nm hptrr
.Nd "HighPoint RocketRAID device driver"
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following line in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device hptrr"
.Cd "device scbus"
.Cd "device da"
.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
hptrr_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for HighPoint's RocketRAID based RAID controllers.
.Pp
These devices support SATA/ATA disk drives
and provide RAID0 (striping), RAID1 (mirroring), and RAID5 functionality.
.Sh LOADER TUNABLES
The following tunables are settable from the loader:
.Bl -tag -width indent
.It Va hw.hptrr.attach_generic
Set to 1 to permit the driver to attach to chips with generic Marvell
(non-HighPoint) PCI identification.
These chips are also supported by
.Xr nata 4 .
.\"and
.\".Xr mvs 4 .
Some vendors are using these chips without providing a RAID BIOS.
.El
.Sh HARDWARE
The
.Nm
driver supports the following RAID
controllers:
.Pp
.Bl -bullet -compact
.It
RocketRAID 172x series
.It

.Pp
This driver does not support the RR182x series controller.
See the
.Xr hptmv 4
manual page for details on support.

.Fx
by
.An Scott Long .
