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 loader.conf(5): hptrr_load="YES"


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 following tunables are settable from the loader: hw.hptrr.attach_generic Set to 1 to permit the driver to attach to chips with generic Marvell (non-HighPoint) PCI identification. These chips are also supported by nata(4). Some vendors are using these chips without providing a RAID BIOS.


The hptrr driver supports the following RAID controllers: o RocketRAID 172x series o RocketRAID 174x series o RocketRAID 2210 o RocketRAID 222x series o RocketRAID 2240 o RocketRAID 230x series o RocketRAID 231x series o RocketRAID 232x series o RocketRAID 2340 o RocketRAID 2522


The hptrr driver only works on the x86_64 platform as it requires a blob from the manufacturer which they only supply for these platforms. This driver does not support the RR182x series controller. See the hptmv(4) manual page for details on support.


cam(4), hpt27xx(4), hptiop(4), hptmv(4), nata(4), loader(8)


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. DragonFly 4.9 June 22, 2015 DragonFly 4.9
