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.
