30.Sh NAME
31.Nm hptrr
32.Nd "HighPoint RocketRAID device driver"
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following line in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device hptrr"
39.Cd "device scbus"
40.Cd "device da"
41.Ed
42.Pp
43Alternatively, to load the driver as a
44module at boot time, place the following line in
45.Xr loader.conf 5 :
46.Bd -literal -offset indent
47hptrr_load="YES"

49.Sh DESCRIPTION
50The
51.Nm
52driver provides support for HighPoint's RocketRAID based RAID controllers.
53.Pp
54These devices support SATA/ATA disk drives
55and provide RAID0 (striping), RAID1 (mirroring), and RAID5 functionality.
5ec55169 56.Sh LOADER TUNABLES
5ec55169
SW
57The following tunables are settable from the loader:
58.Bl -tag -width indent
59.It Va hw.hptrr.attach_generic
60Set to 1 to permit the driver to attach to chips with generic Marvell
61(non-HighPoint) PCI identification.
62These chips are also supported by
63.Xr nata 4 .
64.\"and
65.\".Xr mvs 4 .
66Some vendors are using these chips without providing a RAID BIOS.

96.Sh NOTES
97The
98.Nm
99driver only works on the i386 and x86_64 platforms as it requires a
100blob from the manufacturer which they only supply for these platforms.
101.\"The
102.\".Nm
103.\"driver does
104.\".Em not
105.\"work on i386 with
106.\".Xr pae 4
107.\"enabled.
108.Pp
109This driver does not support the RR182x series controller.
110See the
111.Xr hptmv 4

121.Sh HISTORY
122The
123.Nm
124device driver first appeared in
125.Fx 6.3 .
126.Sh AUTHORS
127.An -nosplit
128The
129.Nm
130device driver was written by
131.An HighPoint Technologies, Inc. ,
132and ported to
133.Fx
134by
135.An Scott Long .
136This manual page was written by
137.An David E. O'Brien .
138.Sh BUGS
139The
140.Nm
141driver does not support manipulating the RAID from the OS, RAIDs need
142to be set up from the on-board BIOS.
