Re: Having both dbwr_io_slaves and disk_asynch_io set

I haven't worked on Solaris in awhile, so I don't n know if the following is true on your version of Solaris or not. I  believe I last tested it on 2.6 or 2.7.

Enabling disk_io_sync on Solaris does not not cause async IO on filesytems, only on raw disk.

You may want to investigate.
