Causa

Problema di risoluzione dei nomi a livello di host vProxy

Resolución

Aggiungere manualmente l'indirizzo IP, l'FQDN, il nome breve di vCenter, Data Domain, NetWorker e storage node in /etc/hosts dell'host vProxy.

Avviare i backup delle VM vProxy ora.
  1. Accedere alla sessione PuTTY vProxy come amministratore, quindi passare a root:
sudo su - root
  1. Eseguire il seguente comando per creare una voce /etc/host
# echo "IP_of_vCenter FQDN_of_vCenter ShortName_of_vCenter" >> /etc/hosts
ESEMPIO: 
# 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
