The solution itself is simple, I flashed the controller in IT-mode.

hard drives determined, zraid, production.
I would like to confirm that I am seeing what appears to be the same issue on my system.
Hardware:
Controller: Broadcom / LSI MegaRAID SAS-3 3008 [Fury]
PCI ID: 1000:005f
Subsystem: 1000:9341
The controller is currently configured in JBOD mode...
