       The lluussddeebbuugg command sets a debugging level for the under-
       lying NetWorker SCSI device drivers.

       Debugging level 0 (zero) turns off debugging.  Larger num-
       bers enable greater levels of debugging.

       The lusdebug level can now be specified as a bitmask - bit
       X set will show messages that are set  to  show  at  debug
       level  X+1.   e.g.  bit 0 set will cause messages at debug
       level 1 to be displayed.  The exact level  for  any  given
       message  is  listed at the end of the message in parenthe-
       ses, such as (8) for a message displayed for  debug  level
       8.

       Using  the bitmask allows you to display any or all levels
       of debugging information.  The old method only allowed you
       to  set  the  highest level you wished to see - all levels
       lower that  the  selected  level  were  always  displayed,
       whether you wanted to see them or not.

       You  may  still specify debugging levels the old way using
       by using the values old1 through old9.  The  results  will
       be displayed using the new bitmask format.

       Values  can be entered in decimal (0 to 65535), hex (0x0 -
       0xffff) or binary (0b0 - 0b1111111111111111).  Zeros after
       the  0x  or 0b prefixes are not required for binary or hex
       values.

       Values that  correspond  to  previous  debug  levels  are:
                      new            new            new

       Invalid debug levels are quietly treated the same as debug
       level zero.

       Debug  level  values  greater  than  65535 (0xffff, binary
       0x1111111111111111)  will  be  treated  as  65535  (0ffff,
       binary..oh, you get the idea...).
