DESCRIPTION
Thesbp
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 problems with such drives, try “camcontrol
[device id] tags -N 1
” to disable tagged queuing.
