[SOLVED] Drives connected with PCI-e controller not showing up. Diagnostics attached.

[leth]

I have recently bought one of those  SAS to SATA controller to add more storage to my workstation. 

I bought a STARTECH.COM SATA PCIe controller 8 port - PCIe x4 Gen2 to SATA III listed as (8P6G-PCIE-SATA-CARD)

 

I currently connected 3 Exos 20TB HDDs and 1 SSD 2TB. 

 

The motherboard is an Asus Pro WS WRX80E-Sage Wifi II

 

It will boot and disks are recognized in the onboard SATA ports.

I can also see and use a couple of m.2 NVME disks connected through an Asus Hyper M2 expansion card.

 

During boot I see some lines I believe to be indication of issues with the recently added drives:

[   13.122194] ata11: found unknown device (class 0)
[   13.125671] ata11: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[   13.129197] ata11: link online but 1 devices misclassified, retrying
[   13.132712] ata11: reset failed (errno=-11), retrying in 10 secs

I'm ready to try out any advice, tips and tricks you may throw my way...

I have already check that;

- disk works in other system (windows)

- power cables changed

- SAS-SATA cables changed

 

I have attached my diagnostics, dump of dmesg, and lspci output - things that was requested in other posts i have found.

I also attached a screenshot of something I think show the expansion card initializing in some way - it shows at least two of the 4 drives attached to the controller for a short time before I can navigate into the BIOS.

If I can provide any other information please let me know and I will get on it ASAP.

Unfortunately tweaking the BIOS settings as "mytech" described did not fix the issue. 

 

I was unable to locate any setting that mentioned "IOMMU".

 

I have attached screenshots of my BIOS settings from the "PCI Subsystem Settings" and "Onboard Devices Configuration". 

Maybe you can spot anything that I may have missed. 

 

In the "Onboard Devices Configuration" tab I can set the lane-mode (hope you know what i mean).
I'm not entirely sure that changing this makes a difference so I went through all of them.. No luck 😕

@JorgeB Ahh okay.. I did not notice this - "pci=realloc=off" - was marked as a solution on a post linked in the post you linked  

I tried adding the best I could but I'm not sure I did it right. Attached the "syslinux.cfg" as I understand it should be put in there. 

 

The drives attached to the controller still doesn't show up 😕 

 

Can anyone confirm it was done right? 

syslinux.cfg

Looks correct.

Hell yea! 

So I finally managed to locate the IMMOU setting - it was berried deep within the BIOS!

Advanced -> AMD CBS -> NBIO Common options -> IOMMU = Disabled

 

.. and that did the trick.
