On a 3584, an "audit library 3584lib checkl=barcode" does NOT cause the
robotics to move and read the barcodes.  It causes TSM to compare its
inventory with the 3584 library's inventory which the library has stored
in memory.  So you first need to cause the 3484 to do an audit (openning
& closing the fron door will do this) and then run the tsm audit library
command.
