title: Disconnecting and reconnecting nvme
body: <p>Is there capacity within amazon/centos/linux to switch the ordering round of nitro disks?</p>
  <p>I have an ami which consistently has devices in the incorrect order, by this I mean nvme1n1 and nvme2n1 should be switched round. If I run <code>nvme id-ctrl -v /dev/nvme1n1 | grep sn</code> I get a different serial number back following a reboot. I know they're &quot;wrong&quot; as the serial numbers are not reflective of their capacity... Hope that makes sense (I appreciate it's a bit confusing). This only ever occurs on servers with two or more disks; upon a reboot the disks are &quot;correct&quot;</p>
  <p>My question is, is there a method of forcing the nvme device to disconnect and reconnect (in the hope that the mapping works as expected in the correct order).</p>
  <p>Thanks guys</p>
