     iopsp - I2O SCSI port driver

SYNOPSIS    [Toc]    [Back]

     iopsp* at iop? tid ?
     scsibus* at iopsp?

DESCRIPTION    [Toc]    [Back]

     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.  For accessing
these, there is
     the ioprbs driver.
