      "description": "This type represents a VNF lifecycle management operation occurrence notification, which informs the receiver of changes in the VNF lifecycle caused by a VNF LCM operation occurrence. The support of the notification is mandatory. This notification shall be triggered by the VNFM when there is a change in the state of a VNF LCM operation occurrence that changes the VNF lifecycle, which represents an occurrence of one the following LCM operations: * Instantiation of the VNF * Scaling of the VNF instance (including auto-scaling) * Healing of the VNF instance (including auto-healing) * Change of the state of the VNF instance (i.e. Operate VNF) * Change of the deployment flavour of the VNF instance * Change of the external connectivity of the VNF instance * Termination of the VNF instance * Modification of VNF instance information and/or VNF configurable\n  properties through the \"PATCH\" method on the \"Individual VNF instance\"\n  resource.\nClause 5.6.2 defines the states and state transition of a VNF LCM operation occurrence, and also specifies details of the notifications to be emitted at each state transition. If this is the initial notification about the start of a VNF LCM operation occurrence, it is assumed that the notification is sent by the VNFM before any action (including sending the grant request) is taken as part of the LCM operation. Due to possible race conditions, the \"start\" notification, the grant request and the LCM operation acknowledgment (i.e. the \"202 Accepted\" response) can arrive in any order at the NFVO, and the NFVO shall be able to handle such a situation. If this is a notification about a final or intermediate result state of a VNF LCM operation occurrence, the notification shall be sent after all related actions of the LCM operation that led to this state have been executed. The new state shall be set in the \"Individual VNF LCM operation occurrence\" resource before the notification about the state change is sent. See clause 5.6.2.2 for further provisions regarding sending this notification, including in cases of handling LCM operation errors.\n",
