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 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.
