SBP(4)                DragonFly Kernel Interfaces Manual                SBP(4)

NAME
     sbp -- Serial Bus Protocol 2 (SBP-2) Mass Storage Devices driver

SYNOPSIS
     kldload firewire
     kldload cam
     kldload sbp

     or

     device sbp
     device firewire
     device scbus
     device da
     device cd
     device pass

DESCRIPTION
     The sbp driver provides support for SBP-2 devices that attach to the
     FireWire (IEEE 1394) port.  It should work with SBP-2 devices which the
     CAM layer supports, for example, HDDs, CDROM drives and DVD drives.

     Note that umass(4) does not detach the device from the CAM layer when the
     device is unplugged.  The idea is to prevent detachment of active
     filesystems due to temporary disconnects or changes in the bus topology.
     You may have to run ``fwcontrol -r'' several times for the system to
     properly detach such devices.

     Some (broken) HDDs don't work well with tagged queuing. If you have prob-
     lems with such drives, try ``camcontrol [device id] tags -N 1'' to dis-
     able tagged queuing.
