In order to present the appearance of a bus, the 54.Nm 55driver groups child peripherals by controlling port. 56.Pp 57On IOPs containing a SCSI port and block or tape driver modules, some SCSI 58devices may not be directly accessible. For each inaccessible device, a 59message will be displayed during configuration. For example: 60.Bd -literal 61 iopsp0: target 0,0 (tid 70): in use by tid 47 62.Ed 63.Pp 64Such devices will usually be indirectly accessible as block devices, either 65individually or as part of an array. 66.Sh SEE ALSO 67.Xr intro 4 , 68.Xr iop 4 , 69.Xr ld 4 , 70.Xr scsi 4 71.Sh HISTORY 72The 73.Nm 74driver first appeared in 75.Nx 1.5.3 . 76.Sh AUTHORS 77The 78.Nm 79driver was written by 80.An Andrew Doran 81.Aq ad@netbsd.org . 82
