**UPDATE
Updated 10.11.4 to 10.11.6, and the ATTO FC-42ES was no longer working. After many failed attempts of reinstalling drivers or OS updates from Mavericks to El Cap, I almost gave up.
My saving grace was from the few hackintosh systems that I built, and discovered that OS X 10.10 and 10.11 updates were simply deleting the old ATTO kext files from the system/library/extensions folder. If I injected the kexts from a working OS X, to 10.10 or 10.11, the FC-42es adapter would continue to work on with out any issues.
Want to save $1,200?! download a kext installer (https://tonymacx86.blogspot.com/2010/08/kextbeast-simple-kext-installer.html)
Then copy your original ATTO kexts, found in the S/L/E folder. Inject the old kexts after you upgraded your OS, and voila!

Just thought I would share this little bit of info… I upgraded to Yosemite from Mavericks a few days ago and learned the hard way that the ATTO FC-42es was no longer recognized. Before I went back to the original Mav config, I went ahead and upgraded to El Cap just for a test. When I did that, mac os x recognized the old ATTO card, and I was actually able to start up XSAN and connect. Saves me $1000 on each ATTO FC-81en
