Disk Async IO

Greetings,

I remember reading Oracle Metalink  Notes saying that Disk Async IO is not
supported on HP-UX for Cooked Filesystems.

We have disk_async_io=true for our Database in HP-UX 11.11 , Oracle
8.1.7.4and 10g Servers.

I would like to ensure that my understanding and setting is right.

Right now we are using 4 dbwr's. I appreciate  your suggestions.

Our UNIX SA says  " Cooked Filesystems have their own Asynchronous
Mechanisim that equally replaces Oracle Async IO"

What Am I missing here

Appreciate your suggestions.
