On Win2012 64 bit, I just upgraded from OMSA 7.4 (32 bit) to OMSA 8.2 (32 bit) and while the storage controller was detected in 7.4, it did not detect the new drives that were just inserted. I hence uninstalled 8.2 (32 bit) and installed 8.3 (64 bit) and it too fails to detect the storage controller.

How do I make OMSA detect the storage controller?

The 4 DSM services are all running.

Server is Dell R720xd.
