Trying to move from an old PC server to a Cisco c240 M3 server. Unraid doesn't see the installed HDD's, I can see them in Cisco's management software but they don't appear in Unraid. I tried disabling VT-d as suggested by a different post but no luck there.

I'm not seeing any controller detected by Linux, what controller does that use?

Sorry i'm not sure what you mean by "controller"

Disks need to be connect to a SATA/SAS controller.

Sorry for the long delay i've been ordering parts and researching like mad. Here is where I stand currently.

 

I installed a 9271-8i raid card. I know the MEGACLI commands to enable IT mode/JBOD but I can't get into the raid card to run any commands as it gives me the error below. I can see the card in the BIOS as occupying the correct PCI-e slot but can't see it in CIMC.

 

I apologize as this is veering away from an unraid issue but countless hours of research and many forum/reddit posts haven't got me anywhere so I'm desperate for any help.

MegaRAID controllers are not recommended, only true HBAs in IT mode, I never used any MegaRAID, so I'm afraid I cannot help with that, if you want to get an HBA see here:

 

 

First off, you have been the only helpful person on the many forums I have posted on so thank you deeply as I have really been spinning my wheels on this.

Follow-up question: 

1. I am using a 12-drive backplane with 2 SFF 8087 breakout plugs. There are no listed 12-drive cards and it seems all of these cards are 4 drives per SFF 8087 plug not 6. Can I get something like the LSI SAS 9207-8i 8Port and just have lower throughput on the drives? Or do I need a different connector or splitter of some sort?

 

 

 

Just to confirm, the backplane only has two SFF 8087 ports? Do you know the model?

Yes only two 8087 ports.

 

I believe it is this one Cisco 74-10197-01 UCS C240 M3 12x3.5" LFF Hard Drive Backplane Board.

It must have an expander, likely the chip below the large heatsink, so you can only connect two ports, it should still have enough bandwidth, assuming it works in dual link mode, you can run the controller tests with the diskspeed docker to confirm performance is OK.

Alright, I am making progress! I can see the drives, and things are mounted however, I am now running into UDMA CRC error counts that keep increasing. It's weird though only the first 4 disks are having increasing CRC errors, which include 3 drives from my previous setup and 1 shucked 10TB drive from an external closure. I have 5 used 2TB drives and those all seem to be fine. I have swapped out cables to troubleshoot, and the HBA (LSI 9207-8i 8Port) is brand new. So not sure what the issue is.

Seems like this is the same issue. 

Will follow this and hopefully it solves it.

 

Damn HBA is already on the most up to date version. What's the next troubleshooting step here?

 

Usually it's a SATA cable issue, are they increasing for all devices?

Nope, it's only increasing for 4 of the 9 drives. Sata Cable from backplane to HBA has been replaced. Could it be a backplane issue?

Could be.
