Hi Adam
Here is the steps, and the server I used is DELL R730xd and DELL R640,
feel free to let me know if you need more info, thanks.
# lspci | grep -i nvme
87:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd
NVMe SSD Controller SM981/PM981/PM983
#echo 1 >/sys/bus/pci/devices/0000\:87\:00.0/remove
#echo 1 >/sys/bus/pci/rescan
Thanks
Yi
