That all depends on how 'check_local_disk' is defined.  Look in your 
checkcommands.cfg (and any other .cfg's you might have) for something 
that looks like this:

define command{
         command_name    check_local_disk
         command_line    $USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$
         }

That defines what 'check_local_disk' means.  In your case, '40%' would 
be $ARG1$, '10%' would be $ARG2$, and '/dev/hda2' would be $ARG3$.

You can manually run 'check_disk' with the '-h' option to see what all 
the options do.
