DESCRIPTION
The
scsi_hba_iport_unit_address() function is used to obtain the unit
address of an iport. For more information on iports, see
iport(9).
This function can be used to determine whether or not a device node in
the tree is an iport. If the device node corresponds to an iport, then
the unit address used when it was created either through
scsi_hba_iport_register(9F) or
scsi_hba_iportmap_iport_add(9F) will be
returned.
CONTEXT
The
scsi_hba_iport_unit_address() function may be called in
user,
kernel, or
interrupt context.
RETURN VALUES
If
dip is an iport, then the unit address string the device was
registered with is returned. Otherwise, NULL is returned.
