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.

HISTORY
     The iopsp driver first appeared in NetBSD 1.5.3.
