Solaris 9 UFS,directIO,async,filesystemio_options

Hi All,

With the enhancement to UFS concurrent direct IO in solaris 9i, I was planning to use UFS for datafiles and still stick with raw volumes for redo logs and temporary tablespace. In this mixed setup, what value should i set for filesystemio_options ? direct io or setall .

also, does async io still go through threaded lwp async emulation or use KAIO for above setup ?. I doubt kaio can work on anything but pure raw volumes or vxfs quick io.

Appreciate any inputs.

Stalin
