NAME
iopsp —
I2O SCSI port driver
SYNOPSIS
iopsp* at iop?
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. For accessing these,
there is the ioprbs driver.
