Informações de Apoio
Falha da função de gerenciamento de sessão (SMF) ao iniciar o serviço quando ocorre um problema; um alerta sobre o Common Execution Environment (CEE) é gerado.
Problema
O SMF-RCDN continua a percorrer a Atualização do Sistema do Ops Center e depois falha.
No CEE, você vê este alerta:

No SMF você vê este erro:

Análise
Para solucionar esse problema, você deve examinar os logs internos do pod do centro de operações SMF.
Neste cenário, o smf-rcdn não iniciou os pods relacionados ao smf.
cloud-user@smf-rcdn-master-1:~$ kubectl get pods -n smf-rcdn

Preparing upgrade logic for helm ...
Dentro dos logs é o motivo pelo qual o sistema falhou ao iniciar. Neste exemplo, o problema ocorreu devido à configuração do sgw-service. O perfil não tem interfaces configuradas.
