NAME
       io_add_to_register_list - autoregister physical disk devices with the
       Virtual Disk Manager

SYNOPSIS
       #include "/usr/src/uts/aviion/ii/i_io.h"

       void          io_add_to_register_list (
           io_device_number_type           device_number   /*READ_ONLY*/
                                             )

DESCRIPTION
       The io_add_to_register_list routine adds the specified device to the
       list of physical disks that will be implicitly registered with the
       Virtual Disk Manager (VDM) during system initialization so that any
       virtual disks on them will become available for use as file systems,
       paging areas, etc.  This routine is optional and is applicable only
       to physical disk device drivers.  The driver's device_configure rou­
       tine should call io_add_to_register_list only near the end of a suc­
       cessful configuration operation.

DIAGNOSTICS
   Return Value
       None.

   Errors
       None.

   Abort Conditions
       None.
