PERC H965i not seeing nvme drives

tjansen1556,

The issue you are seeing, with the drives visible to the software controller but not the hardware controller, is likely due to cabling. When you add a hardware controller the cabling to the backplane will change between the two, as well as varies if it is an H965i adapter or front perc. You can find the different variances here and let us know the most accurate one then we can see about locating the correct cable you will need. 

Let me know if this helps.

Pretty sure this happened to me as well. Ordered through account manager and engineer. Specified I needed nvme raid. Got a config with front perc 12 and 8 2.5inch bays. When I look at the diagram for my model it matches the non raid config.

Of course my account manager assured me it's configured correctly. Two hrs on phone with support and support came to the conclusion it's wired incorrectly. But only account manager can fix it.

Emailed her back and got an auto responder.

You guys need to train your engineers

Word to the wise Linux is easy to identify this issue: lspci

@DELL-Chris H ​ We do have the same problem.. We have ordered a poweredge R6726 including perc controller H965i

So the controller see’s the disks, however does not allow us to create a hardware raid or volume 

I read somewhere that the configuration might be different and in order to get hardware raid on nvme some cabling might need to be different, So vmware see’s the disks and they are showing in the controller, but won’t allow us to create a raid, I had also enabled the setting about the non dell disks last night, but it did not help unfortunately .

The Dell official documentation clearly states that HW raid on H965i including NVME disks is supported . Can you advise way forward and what is required ? Service Tag:<Private data removed from public view. DELL-Admin>

Hello,

I want to share something came to my mind regarding your issue, first please ensure your NVMe drives are Dell-certified, as non-Dell drives might not be recognized due to firmware issues. Dell supports NVMe drive speeds of 8 GT/s (Gen 3) and 16 GT/s (Gen 4) at a maximum x2 lane width. However, Dell does not officially support NVMe drives with EEDP enabled, even if the feature is active. You can check this feature on your drives.

Hope that helps!

@DELL-Erman O​ I beleive that is not the issue. The disks are visible on Idrac/bios etc however we cannot configure HW RAID on the NVME disks. Its seems this is a know issue as some type of backplane cabling needs adjusting
