Solution
You can enable Async I/O by modifying the fs_async Kernel parameter. It is set to 0 (sync. I/O) by default. Change it to 1 and you should be in business. You can find this and lots of other great tuning tips in the HP-UX Kernel Tuning and Performance Guide which is available all over the net. Here is the link I found:

Hope that this helps.
Good Luck,

Re: Asynchronous I/O
The kernel parameter fs_async ( a value of 1 ) will enable asynchronus I/O . But I believe its not only for one logical volume , it will affect all the logical volumes.
