How about truss/strace equivalent on HP-UX on dbwr
to see whether its using AIO or not. If AIO fails
then it will follow by a normal IO call.

/dev does not have an async
Ethan -
it has been a while and we don't have an HP-UX box here, but if memory
serves the missing /dev/async is a dead giveaway that your not using async
io.
to use async io on HP-UX we had to install something called the asyncdisk
driver in SAM and then use mknod to create /dev/async
The HP-UX syscall tracing tool is called 'tusc', and it's supposed to be
available by visiting ftp://ftp.cup.hp.com/dist/networking/misc/.

On HP, I believe that async I/O is only supported for raw filesystems. See
MetaLink for more details.
