DESCRIPTION
       The ldi_strategy() function passes a strategy request to the device entry point for the device specified by the layered handle. This opera-
       tion is supported for block devices.

       Once the request has been passed on to the target devices strategy entry point, any further errors will be  reported  by  bioerror(9F)  and
       biodone(9F). See the strategy(9E) entry point for more information.
