Cause

Namnmatchningsproblem på vProxy-värdnivå

Resolution

Lägg till IP-adress, FQDN manuellt, kortnamn för vCenter, Data Domain, NetWorker och lagringsnod i /etc/hosts på vProxy Host.

Starta vProxy VM-säkerhetskopieringar nu.
  1. Logga in på vProxy PuTTY-sessionen som administratör och växla sedan till root:
sudo su - root
  1. Kör följande kommando för att skapa en /etc/host-post
# echo "IP_of_vCenter FQDN_of_vCenter ShortName_of_vCenter" >> /etc/hosts
PROV: 
# 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
