In one of our recently(almost a month) upgraded apps instance from 9.2.0.5 to 10.2.0.2,we left disk_async_io=true but we dont get any errors related to note:394870.1,though i believe and as discussed that HP-UX(jfs) doesnt have asynchronous I/O.
still today its set as disk_async_io=true!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

In 10.2.0.2+ on HP-UX PA-RISC - Disk Aynch I/O is enabled by default (or mistake).
If /dev/async file is not found (most likely not), you will see a number of little trace
files with a message stating as such. DISK_ASYNCH_IO must be manually set to FALSE to
stop the generation of these trace files.
