32 .Nd scsi user-level driver
34 .Cd "pseudo-device su"
38 driver provides support for a
39 process to address arbitrary locations on the scsi bus. Minor
40 numbers are mapped 1:1 to bus:target:lun. The lowest three bits being LUN
41 and the next three bits being TARGET. Remaining bits are the bus number.
43 A scsi adapter must also be separately configured into the system
44 before this driver makes sense.
46 .Sh KERNEL CONFIGURATION
47 There are no configuration parameters for the su option. It's either there
54 driver has no ioctls of it's own but rather acts as a medium for the
57 ioctls. These are described in
62 .Bl -tag -width /dev/su0-0-0XXXXXXXXXXX -compact
63 .It Pa /dev/su[0-9]-[0-7]-[0-7]
64 su{x}-{y}-{z} is the su device for the device at bus x, target y, lun z
