Both of them are equipped with 24x Intel P DC4500 U.2 devices, which are obviously hot-pluggable, at least they seem to be. ;)</div><div><br></div><div>At the moment, I am trying to familiarize myself with the handling of those devices and I am having quite a hard time, coming up with a method of safely removing/replacing such a device. I am able to detach a nvme device using nvmeadm, but removing it from the system by pulling it out, causes the kernel to retire the pci device and I have not yet found a way to get the re-inserted device online again.</div><div><br></div><div>Anybody having some experience how to handle those NVMe devices?</div><div><br></div><div>Thanks,</div><div>Stephan</div><div><div><br></div></div></div></body></html>
