NAME

       raidstart, raidstop, - command set to manage md devices.

SYNOPSIS

       raidstart [options] <raiddevice>*

       raidstop [options] <raiddevice>*

DESCRIPTION

       RAID  devices  are  virtual  devices  created  from two or more real block devices. This allows multiple disks to be combined into a single
       filesystem, possibly with automated backup and recovery. Linux RAID devices are implemented through the md device driver.

       If you're using the /proc filesystem, /proc/mdstat gives you informations about md devices status.

       Currently, Linux supports linear md devices, RAID0 (striping), RAID1 (mirrroring), and RAID4 and RAID5. For information on the various lev-
       els of RAID, check out:

	    http://ostenfeld.dk/~jakob/Software-RAID.HOWTO/

       for new releases of the RAID driver check out:

	    ftp://ftp.fi.kernel.org/pub/linux/daemons/raid/alpha

       Avaible commands are :

       mkraid : configures (creates) md (RAID) devices in the kernel, banding multiple devices into one.

       raidstart : activates (starts) an existing 'persistent' md device

       raid0run : activates old nonpersistent RAID0/LINEAR md devices

       raidstop : turns off an md device, and unconfigures (stops) it

       By default, a systems RAID configuration is kept in /etc/raidtab, which can configure multiple RAID devices.

       All  of	these  tools  work similiarly. If -a (or --all) is specified, the specified operation is performed on all of the RAID devices men-
       tioned in the configuration file. Otherwise, one or more RAID devices must be specified on the command line. For example:

       raid0run -a

       Starts all of the 'old' RAID0 RAID devices specified in /etc/raidtab. If only /dev/md1 should be started, the following command	should	be
       used instead:

       raidstart /dev/md1

OPTIONS

       -a, --all
	      Apply the command to all of the configurations specified in the config file.

       -c, --configfile filename
	      Use filename as the configuration file (/etc/raidtab is used by default).

       -h, --help
	      Displays a short usage message, then exits.

       -V, --version
	      Displays a short version message, then exits.

NOTES

       The  raidtools  are  derived from the md-tools and raidtools packages, which were originally written by Marc Zyngier, Miguel de Icaza, Gadi
       Oxman, Bradley Ward Allen, and Ingo Molnar.

BUGS

       no known bugs.

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 0 to deny driver attach to chips with generic Marvell (non-HighPoint) PCI identification. These chips are also supported by ata(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), 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.
