.Sh SYNOPSIS

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