Starting DHCP server and configuring PXE boot environment is not part of this

State machine diagram
|
||||
=====================
|
||||
|
||||
The diagram below shows the introspection states that an **ironic-inspector**
|
||||
FSM goes through during the node introspection, discovery and reprocessing.
|
||||
The diagram also shows events that trigger state transitions.
