NAME
hptrr -- HighPoint RocketRAID device driver SYNOPSIS
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 following tunables are settable from the loader: 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 ata(4) and mvs(4). Some vendors are using same chips, but without providing RAID BIOS. DESCRIPTION
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. HARDWARE
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 NOTES
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. SEE ALSO
ata(4), cam(4), hptmv(4), mvs(4), loader(8) HISTORY
The hptrr device driver first appeared in FreeBSD 6.3. AUTHORS
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. BUGS
The hptrr driver does not support manipulating the RAID from the OS, RAIDs need to be set up from the on-board BIOS. BSD

NAME
ataraid -- ATA software RAID support SYNOPSIS
device ata device ataraid DESCRIPTION
The ataraid driver provides support for so-called software RAID (sometimes referred to as fake RAID or pseudo RAID). When a controller that supports software RAID is instructed to create a RAID array, its BIOS writes data structures in a specific metadata format to the disks. These data structures are picked up by the ataraid driver, so that FreeBSD can work with the array. The ataraid driver has to understand the specific metadata format of a controller BIOS in order to support its RAID capabilities. Read-only support for a metadata format means that FreeBSD can use the given RAID array for normal read/write operations. Creation and rebuild of such arrays has to be done from the controller BIOS. Read and write support for a metadata format means that FreeBSD can use the given RAID array for normal read/write operations. Additionally, the atacontrol(8) utility can be used to create, rebuild, update and fail such RAID arrays. The ataraid driver can read the following metadata formats: o Adaptec HostRAID o Highpoint V2 RocketRAID o Highpoint V3 RocketRAID o Intel MatrixRAID o Integrated Technology Express (ITE) o JMicron o LSI Logic V2 MegaRAID o LSI Logic V3 MegaRAID o NVIDIA MediaShield o Promise FastTrak o Silicon Image Medley o Silicon Integrated Systems (SiS) o VIA Tech V-RAID o FreeBSD PseudoRAID The ataraid driver can write the following metadata formats: o Highpoint V2 RocketRAID o Intel MatrixRAID o JMicron o Promise FastTrak o Silicon Integrated Systems (SiS) o VIA Tech V-RAID o FreeBSD PseudoRAID It is also possible to use software RAID on controllers that do not have special software RAID capabilities. See atacontrol(8) for details. FILES

RAID5 is not supported at this time. Code exists, but it neither uses nor maintains parity information. AUTHORS
