Well I dont think I'm going to get much help with this. But I thought I would give it a shot.
I got this large peice of poop Qnap server. 24 drive bay.
anyway it had 48gig of ESS ram and a Xeon 2136 CPU 6 core with Hyper Threads.
anyway I add a video card so I could get to the bios to change the boot order. But I cant get any Linux OS's to see more than 8 Drive bays.

Any suggestions?

 

You can post the diagnostics to see if something is visible there.

Ok I'll do that and start a new thread. I tried reloading the server with TrueNAS Scales and same issue. I might try Core Version and see if BSD OS can see the drives. But I'm suspecting not.
I have a feeling its most likely using a Marvel controller and it most likely will never work. Which is disappointing but if thats the case. This makes me a little miffed. I like this free piece of crap I got. Just dont like Qnap OS.

 

Sorry I was going to do a new thread but I think that could be a bad Idea. Here is the Diag.

At least one of the controllers uses SATA port multipliers, so it would not be recommended for Unraid, but all controllers appear to be initializing correctly.

Well that must be what is going on then because I can only see 8 drive bays and the 2 NVME's on the PCI-E Card. I would have no Idea how I could change the back plane to use Some sort of HBA connectors. I guess that would be my next attempt. 

I almost want to grab the 12 bay one and take it home and try that one instead. Only small problem is I don't have a small form Video card I can use to get into the Bios.

None of these models have a external display port so I have to add a Video card to just get into bios to change the boot order. 

Also the 12bay the Processor is just a 4c with Hyper threading. So I would have to change the processors around just to get that. But If I find its worth it and all bays work. I might consider it. Thanks for checking that over and letting me know.

Now I need to learn where to see what your talking about in the log to see that so I dont have to ask so many questions.
