Cause

O gateway do PowerFlex não consegue se conectar ao cluster principal do MDM quando a função principal é alternada com frequência entre diferentes membros do cluster do MDM. Isso foi observado durante a reconfiguração do MDM, quando várias funções do MDM precisam ser movidas.

Resolution

Para corrigir esse problema, o usuário deve reiniciar o pod do gateway do PowerFlex.

O seguinte comando pode ser usado para reiniciar o gateway do PowerFlex.

kubectl delete pod -n powerflex $(kubectl get pods -A | grep block-legacy-gateway | grep -v mds | grep -i running | awk ' {print $2}')
