VnfLcmOperationOccurrenceNotification:
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 VNF lifecycle caused by a VNF LCM operation occurrence,
including:
* 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
properties through the "PATCH" method on the "Individual VNF instance"
resource.
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 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.
