 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"
 48.Ed
 49.Pp
 50The following tunables are settable from the loader:
 51.Bl -ohang
 52.It Va hw.hptrr.attach_generic
 53set to 1 to permit driver attach to chips with generic Marvell (non-HighPoint)
 54PCI identification. These chips are also supported by
 55.Xr ata 4
 56and
 57.Xr mvs 4 .
 58Some vendors are using same chips, but without providing RAID BIOS.
 59.El
 60.Sh DESCRIPTION
 61The
 62.Nm
 63driver provides support for HighPoint's RocketRAID based RAID controllers.
 64.Pp
 65These devices support SATA/ATA disk drives
 66and provide RAID0 (striping), RAID1 (mirroring), and RAID5 functionality.
 67.Sh HARDWARE
 68The
 69.Nm
 70driver supports the following RAID
 71controllers:

 73.Bl -bullet -compact
 74.It
 75RocketRAID 172x series
 76.It
 77RocketRAID 174x series
 78.It
 79RocketRAID 2210
 80.It
 81RocketRAID 222x series
 82.It
 83RocketRAID 2240
 84.It
 85RocketRAID 230x series
 86.It
 87RocketRAID 231x series
 88.It
 89RocketRAID 232x series

 91RocketRAID 2340
 92.It
 93RocketRAID 2522
 94.El
 95.Sh NOTES
 96The
 97.Nm
 98driver only works on the i386 and amd64 platforms as it requires a binary
 99blob object from the manufacturer which they only supply for these platforms.
100The
101.Nm
102driver does
103.Em not
104work on i386 with
105.Xr pae 4
106enabled.
107.Pp
108This driver does not support the RR182x series controller.
109See the
110.Xr hptmv 4
111manual page for details on support.
112.Pp
113This driver supersedes the older rr232x driver.

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