.Dd November 8, 1999 .Dt IOPSP 4 .Os .Sh NAME .Nm iopsp .Nd I2O SCSI port driver .Sh SYNOPSIS .Cd "iopsp* at iop? tid ?" .Cd "scsibus* at iopsp?" .Sh DESCRIPTION The .Nm driver provides support for I2O SCSI bus adapter ports and child peripherals.
p IOPs present each child peripheral attached to a bus adapter port as an individual device. In order to present the appearance of a bus, the .Nm driver groups child peripherals by controlling port.
p On IOPs containing a SCSI port and block or tape driver modules, some SCSI devices may not be directly accessible. For each inaccessible device, a message will be displayed during configuration. For example: d -literal iopsp0: target 0,0 (tid 70): in use by tid 47 .Ed
p Such devices will usually be indirectly accessible as block devices, either individually or as part of an array. .Sh SEE ALSO .Xr intro 4 , .Xr iop 4 , .Xr ld 4 , .Xr scsi 4 .Sh HISTORY The .Nm driver first appeared in .Nx 1.5.3 .
