What is the difference between the "UP" state and the "UP (restart required)" state

The "UP (restart required)" state explains that the node is currently up, however, the configuration was changed and a reboot of the node is required for the change to take affect.

An example of some configuration changes that can trigger the "restart required" flag.

  1. Kernel version has changed. (Category or device level)
  2. Kernel parameters have changed. (Category or device level)
  3. Network configuration has changed (new interface was added, existing interface modified on a node.
  4. The software image of a node was changed.  (Category or device level)
