Cause

Navneoversættelsesproblem på vProxy-værtsniveau

Resolution

Tilføj manuelt IP-adressen, FQDN, det korte navn på vCenter, Data Domain, NetWorker og Storage Node i /etc/hosts for vProxy Host.

Start vProxy VM-sikkerhedskopieringer nu.
  1. Log på vProxy PuTTY-sessionen som admin, og skift derefter til root:
sudo su - root
  1. Kør følgende kommando for at oprette en /etc/host-post
# echo "IP_of_vCenter FQDN_of_vCenter ShortName_of_vCenter" >> /etc/hosts
PRØVE: 
# 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
