In order to present the appearance of a bus, the 47.Nm 48driver groups child peripherals by controlling port. 49.Pp 50On IOPs containing a SCSI port and block or tape driver modules, some SCSI 51devices may not be directly accessible. For each inaccessible device, a 52message will be displayed during configuration. For example: 53.Bd -literal 54 iopsp0: target 0,0 (tid 70): in use by tid 47 55.Ed 56.Pp 57Such devices will usually be indirectly accessible as block devices, either 58individually or as part of an array. 59.Sh SEE ALSO 60.Xr intro 4 , 61.Xr iop 4 , 62.Xr ld 4 , 63.Xr scsi 4 64.Sh HISTORY 65The 66.Nm 67driver first appeared in 68.Nx 1.5.3 . 69
