Description

   The function sends a SCSI Initialize Element Status command to
   the specified robot. This command is not supported by the TA and
   TF loaders. On robots where this command is supported, it forces
   a physical reinventory of the library or loader. On some library
   systems this may take a long time.

   Most library subsystems will perform an inventory when they are
   powered on or have detected that the configuration may have
   changed (doors opened, panels removed, etc). For this reason,
   this routine is rarely needed.
