IOPSP(4)                  OpenBSD Programmer's 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 iop-
     sp driver groups child peripherals by controlling port.

     On IOPs containing a SCSI port and block or tape driver modules, some SC-
     SI 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, ei-
     ther individually or as part of an array.  For accessing these, there is
     the ioprbs driver.
