I checked all my connections, from the drive to the JBOD, to the Cable going to the HBA card in the server. The drives are still not coming up in Unraid. When you checked the logs, did you see all 17 disks initialize? I'm sorry, I don't know where to look in the diagnostics to check that my self.
Also, I do have 2 HBAs in the server. One internal for the server's backplane and one external for the JBOD.
