Cause

Problema de resolución de nombres en el nivel de host de vProxy

Resolution

Agregue manualmente la dirección IP, el FQDN, el nombre corto de vCenter, Data Domain, NetWorker y el nodo de almacenamiento en /etc/hosts del host vProxy.

Inicie los respaldos de VM de vProxy ahora.
  1. Inicie sesión en la sesión de PuTTY de vProxy como administrador y, a continuación, cambie a root:
sudo su - root
  1. Ejecute el siguiente comando para crear una entrada /etc/host
# echo "IP_of_vCenter FQDN_of_vCenter ShortName_of_vCenter" >> /etc/hosts
MUESTRA: 
# echo "10.10.10.10 myvcenter.abc.com myvcenter" >> /etc/hosts
# echo "IP_of_DD FQDN_of_DD ShortName_of_DD" >> /etc/hosts
# echo "IP_of_NWServer FQDN_of_NWServer ShortName_of_NWServer" >> /etc/hosts
# echo "IP_of_StorageNode FQDN_of_StorageNode ShortName_of_StorageNode" >> /etc/hosts
