Disks not recognized when using Dell H710

[overwhelmed]

Hello,

 

I have an issue with my disks not being recognized. Up until today I had them connected to both the motherboard SATA ports as well as to a simple PCIE SATA extender. MB is Supermicro X11SAE-M.

 

Today I have added Dell H710 card which I had in another testing system where it worked just fine. I plugged all my disks except NVME and one SSD into it but unRAID doesn't see them. I checked BIOS and the card is recognized there as are all disks plugged into it. The card is flashed to IT mode and like I wrote, worked just fine in another system.

 

Any suggestions what I could do?

 

Attached are my diagnostics.

The Dell controller is not being detected by Linux, this is not a software issue, try a different PCIe slot if available

Thank you! I've tried a different slot, the main one, 3.0 x16, in which I have a GPU, and it works there. Anything I can do to make it work in the previous slot, 3.0 X4, so I can keep using the GPU?

Thank you. I thought that was PCI-e 2.0 x8 and thought that the bandwidth of 3.0 x4 would suffice.

 

Also, apologies for the stupid question, but why did it show up correctly in BIOS with all disks (checked them one by one) but then didn't work? Was it hitting a bandwidth limit or something?

They usually work with fewer lanes, with limited bandwidth, but that can be controller specific and I'm not familiar with that model, an LSI HBA should work fine in an x4 slot, and preferable to a RAID controller in HBA mode, since it's never a true HBA.
