Angie Journal,  The Windows 2012 driver I believe you will be needing is located here. Let me know how it goes and if everything resolves itself after the update.
We have a new Vrtx (shipped this summer) with M630 blades. After the initial OS install (windows 2012 datacenter R2), their were only two devices that had no driver installed - they were both raid controllers. The OS was deployed via the Lifecycle controller running the latest package. After doing windows updates, both those raid controllers were updated to "Shared Perc 8".  After the driver update, the "shared perc 8" has a driver 3/15/2013 6.801.5.0 that points to windows\system32\drivers\percsas2.sys.  The driver has an error saying it cannot start (code 10). An I/O adapter hardware error has occurred. I've seen that you should obtain a driver for "shared perc 8" from Dell. But I cannot find that driver anywhere. Does anyone know where to obtain a newer driver for this controller? Any help will be appreciated.  AJ
