42 driver provides support for I2O SCSI bus adapter ports and child
45 IOPs present each child peripheral attached to a bus adapter port as an
46 individual device. In order to present the appearance of a bus, the
48 driver groups child peripherals by controlling port.
50 On IOPs containing a SCSI port and block or tape driver modules, some SCSI
51 devices may not be directly accessible. For each inaccessible device, a
52 message will be displayed during configuration. For example:
54 iopsp0: target 0,0 (tid 70): in use by tid 47
57 Such devices will usually be indirectly accessible as block devices, either
58 individually or as part of an array.
