Abstract
An example operation may include a system, comprising one or more of receiving a VNFCI status notification resumption with an active state, retrieving a timestamp of the VNFCI state change to active, retrieving a timestamp of a peer VNFCI state change to active, checking with a VIM to determine if the VNFCI network isolated while active, checking with the VIM to determine if the peer VNFCI network isolated while active, sending a first state change request message with standby to the peer VNFCI when one or more of: the peer VNFCI was network isolated, and the VNFCI was not network isolated, sending a second state change request message with standby to the peer VNFCI when one or more of: the VNFCI is not the preferred standby instance, and the peer VNFCI was not network isolated, and the VNFCI was not network isolated, starting a first retry timer for the peer VNFCI when one or more of: the first state change request message is sent, and the second state change request message is sent, sending a third state change request message with standby to the VNFCI when one or more of: the VNFCI is the preferred standby instance, and the peer VNFCI was network isolated, and the VNFCI was network isolated, sending a fourth state change request message with standby to the VNFCI when one or more of: the peer VNFCI was not network isolated, and the VNFCI was network isolated, and starting a second retry timer for the VNFCI when one or more of: the third state change request message is sent, and the fourth state change request message is sent.
