Cheng,    

  the raw files system is for solaris server.    

  We are using normal Filesystem.
  Already Async io is set in couple of other HP-UX servers........    

  on what basis can we change disk_asynch_io = FALSE to disk_asynch_io = TRUE (PLease see below information for clarity of my requirement)    

  Any docs pertaining to disk_asynch_io = TRUE and its Advantages    

  Thanks,
  Edwin.K

  You need to setup raw devices to use AIO in HP-UX. No chance if you are using vxfs.
