Hi,
I have a system on Oracle Linux 9.X customized system unit ("uname -a" output:Linux AP6400-P1.0B-000387 5.15.0 #15 SMP PREEMPT Wed Jun 26 18:07:02 UTC 2024 x86_64 GNU/Linux). When commanded "nvme list"("nvme version" output: nvme version 2.4 (git 2.4),libnvme version 1.4 (git 1.4)), the output is blank as below:

"nvme list -v" command output:

Talked with nvme online support, and after a few posting exchanged, he pointed out that issue was caused by the Linux Kernel configuration, since it missed nvme0n1 in /sys/class/nvme/nvme0/. I checked the system, and nvme0n1 was not in /sys/class/nvme/nvme0/.
Would someone know what caused it, and how to fix it?
Thanks
Gansheng
