February 4, 20197 yr So I just purchased a Supermicro 836, new Supermicro X10SRL-F, installed 16GB of recommended Supermicro RAM, flashed 2 9211-8i's to IT mode successfully. Plugged everything in, and unRAID just says "too many incorrect disks". It looks from the main page that it sees 3 random disks. Can anyone tell me what I've done incorrectly? tower-diagnostics-20190204-0313.zip
February 4, 20197 yr Author During boot the 9211 BIOS screen goes by and says something about configuration changes but when I enter it, I don't seem to have many options to change anything. I think this is definitely the problem. Should I get an SAS expander instead of 2 9211 8is? If so, which one would anyone recommend with this card? I've never really used one before.

February 4, 20197 yr Community Expert Disks are just not being detected, if they don't appear on the HBA bios they also won't appear on Unraid, what is the backplane model?
February 4, 20197 yr Author SuperMicro CSE-836A-R1200B> I really hope this isn't incompatible as several people from the forums told me that there are "great deals on supermicro 836 cases on ebay".... I wouldn't think it's entirely incompatible as it does see some drives. I think it's just that the BIOS for both cards is not loading correctly.
February 4, 20197 yr Community Expert I was asking the backplane model, looks like that chassis only comes with the BPN-SAS-836A, if so that's a direct connection backplane with sff-8087 cables, so no chance of getting the wrong cables, check all power/SAS connections, if both HBAs don't detect any disks it's likely a backplane problem.
February 4, 20197 yr Author They do detect some disks. But with both 9211s when the bios loads it identifies one properly and the other unsuccessfully. I will report back when I get my SAS expander. Which I have verified works with the 9211 in it mode.
