Hi All,
I have been trying to use Linux NVMe dirver for testing hotplug on HP and dell servers. But I see some problems. So I wanted to know if the opensource NVMe driver supports 'hotplug', or any code changes required to support the feature?
All the hotplug related modules acpiphp, pciehp and pci_hotplug were loaded before performing tests. The first problem seen is that the device is not detected once the surprise remove-inertion is done. Second is that, the device gets detected sometime after surprise remove-inertion, but the IOs do not resume on the device. The application just hangs.
Any pointers on what should be done to make it work. I would appreciate the help.
Thanks in advance.
