The driver 54provides no support for targets with multiple logical unit numbers 55(LUNs). 56.Sh SEE ALSO 57.Xr intro 4 , 58.Xr rz 4 , 59.Xr tz 4 , 60.Xr sd 4 , 61.Xr st 4 , 62.Xr cd 4 , 63.Xr ch 4 . 64.Sh HISTORY 65The 66.Nm 67driver first appeared in 68.Bx 4.4 . 69.Sh BUGS 70The 71.Nm 72driver only supports the 73.Nm oldscsibus 74higher-level layer, and the 75.Nm rz 76and 77.Nm tz 78devices, which first appeared in 79.Bx 4.4 /pmax. 80It should be re-written to support the 81.Nm scsibus 82machine-independent higher-level SCSI layer and the 83.Nm sd , 84.Nm st , 85and 86.Nm cd 87drivers.
