Cause

vProxyホスト レベルでの名前解決の問題

Resolution

vProxyホストの/etc/hostsに、vCenter、Data Domain、NetWorker、ストレージ ノードのIPアドレス、FQDN、短い名前を手動で追加します。

vProxy VMバックアップを今すぐ開始します。
  1. vProxy PuTTYセッションにadminとしてログインし、rootに切り替えます。
sudo su - root
  1. 次のコマンドを実行して、/etc/hostエントリーを作成します。
# echo "IP_of_vCenter FQDN_of_vCenter ShortName_of_vCenter" >> /etc/hosts
サンプル： 
# 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
