WOW! I updated the firmware on the MD3200 to latest 08.20.18.60 and everything appeared to go well. Now one controller is not visible in MSDM and I get a "needs attention" message indicating the SAS ports failed on both controllers. Drives are all visible within MSDM so the controller has life.
How can a firmware update that goes well yield this result? Unit is not under support any longer, so I'm hoping someone can point me in the right direction to hopefully resolve this.
