     hptrr — HighPoint RocketRAID device driver


     To compile this driver into the kernel, place the following line in your kernel
     configuration file:

           device hptrr
           device scbus
           device da

     Alternatively, to load the driver as a module at boot time, place the following line in


     The following tunables are settable from the loader:

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


     The hptrr driver provides support for HighPoint's RocketRAID based RAID controllers.

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


     The hptrr driver supports the following RAID controllers:

        RocketRAID 172x series
        RocketRAID 174x series
        RocketRAID 2210
        RocketRAID 222x series
        RocketRAID 2240
        RocketRAID 230x series
        RocketRAID 231x series
        RocketRAID 232x series
        RocketRAID 2340
        RocketRAID 2522


     The hptrr 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 hptrr driver
     does not work on i386 with pae(4) enabled.

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

     This driver supersedes the older rr232x driver.

     The hptrr device driver first appeared in FreeBSD 6.3.


     The hptrr device driver was written by HighPoint Technologies, Inc., and ported to FreeBSD
     by Scott Long.  This manual page was written by David E. O'Brien.


     The hptrr driver does not support manipulating the RAID from the OS, RAIDs need to be set up
     from the on-board BIOS.
