openflags=o_direct on HP-UX

user2308403Nov 5 2018

Hi

Recently started to use vdbench.  Working well on our Linux hosts, however am trying to perform test from our HP-UX hosts.  I have downloaded the shared library from another thread and it's generally working, however when I try and use openflags= on the sd definition I'm greeted with the error: -

* Slave localhost-0 aborting: 'openflags=' parameter is only valid when the target system is Solaris, Linux, Windows, MAC or AIX.  *

Is there any way to get this option working on HP?

I've tried using raw disk devices over block devices (i.e. /dev/rdisk) however the throughput is much lower than I can generate with iozone on the same host using O_DIRECT, so it's clearly not the same.

Thanks
