.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
.Pp
The following tunables are settable from the loader:
.Bl -ohang
.It Va hw.hptrr.attach_generic
set to 0 to deny driver attach to chips with generic Marvell (non-HighPoint)
PCI identification. These chips are also supported by ata(4).
Some vendors are using same chips, but without providing RAID BIOS.
.El
.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 HARDWARE
The
.Nm
driver supports the following RAID
controllers:
.Pp
.Bl -bullet -compact
.It
RocketRAID 172x series
.It
RocketRAID 174x series
.It
RocketRAID 2210
.It
RocketRAID 222x series
.It
RocketRAID 2240
.It
RocketRAID 230x series
.It
RocketRAID 231x series
.It
RocketRAID 232x series
.It
RocketRAID 2340
.It
RocketRAID 2522

.Sh NOTES
The
.Nm
driver only works on the i386 and amd64 platforms as it requires a binary
blob object from the manufacturer which they only supply for these platforms.
The
.Nm
driver does
.Em not
work on i386 with
.Xr pae 4
enabled.
.Pp
This driver does not support the RR182x series controller.
See the
.Xr hptmv 4
manual page for details on support.
.Pp
This driver supersedes the older rr232x driver.

.Sh HISTORY
The
.Nm
device driver first appeared in
.Fx 6.3 .
.Sh AUTHORS
.An -nosplit
The
.Nm
device driver was written by
.An HighPoint Technologies, Inc. ,
and ported to
.Fx
by
.An Scott Long .

.An David E. O'Brien .
.Sh BUGS
The
.Nm
driver does not support manipulating the RAID from the OS, RAIDs need
to be set up from the on-board BIOS.
