IOPSP(4)						   BSD Kernel Interfaces Manual 						  IOPSP(4)

NAME
iopsp -- I2O SCSI port driver SYNOPSIS
iopsp* at iop? tid ? scsibus* at iopsp? DESCRIPTION
The iopsp driver provides support for I2O SCSI bus adapter ports and child peripherals. 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 iopsp driver groups child peripherals by controlling port. 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: iopsp0: target 0,0 (tid 70): in use by tid 47 Such devices will usually be indirectly accessible as block devices, either individually or as part of an array. SEE ALSO
