This could be related to the Operating system you are using. CentOS 7.4 needs the drivers installed before, in order to recognize those M.2
Try to check the type of onboard controller that the server board is using to handle those drives (AHCI, ESRT2) and then get the drivers to load. As an additional step and for testing purposes only, try one of those nodes (if possible) with another operating system, either Windows or Linux, and check if the drives get recognize.
* The controllers are all set to AHCI mode
* CentOS 7.4 can detect the AIC form factor PCIe SSDs (P4600) in the same system. It has the nvme driver loaded, yet doesn't see the M.2 SSD. Is there some additional driver that needs to be installed?
Note: I'm not trying to boot off the M.2 SSD, I'm just trying to detect it from the OS after the OS boots up (OS installed on a SATA SSD)
Please try the following driver:
Let me know if that helps you.
Have a nice weekend!
Hi, thanks for reaching out,
Just to check some basics there:
Your OS is not capable to find the rive because is missing the required driver for it, at this moment, there is no Linux support for this hardware, the only available drivers existing are for Windows please, check: Downloads for Intel® SSD E 6100p Series (128GB, M.2 80mm PCIe 3.0 x4, 3D2, TLC) as a reference
Have you had the chance to review the article System Requirements for Operating System Installation on a PCIe* NVMe* SSD? That one in particular is for booting drive but it defines the general requirement s for using the technology.
For testers you could try to install one of the windows versions described in the article parallel to your CentOS then install the driver and map the drive from the device manager, so we can confirm the board is capable to allow access to the drive from OS.
Should you have further questions or concerns please let me know.
