.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 1 to permit driver attach to chips with generic Marvell (non-HighPoint)
|
|
PCI identification.
|
|
These chips are also supported by
|
|
.Xr ata 4
|
|
and
|
|
.Xr mvs 4 .
|
|
Some vendors are using same chips, but without providing RAID BIOS.
|
|

These devices support SATA/ATA disk drives
|
|
and provide RAID0 (striping), RAID1 (mirroring), and RAID5 functionality.
|
|

.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.
