NVMe devices not found under the /dev
directory after
PCI rescan
After removing the PCI bus of NVM Express (NVMe) adapter card
devices and running a rescan of the PCI bus, no NVMe adapter
card devices are found under the /dev
directory.
The workaround for this issue is to also remove the PCI slot that the NVMe adapter card device is plugged into before running a rescan of the PCI bus. (Bug ID 26610285)
