Cause

vProxy 호스트 레벨의 이름 확인 문제

Resolution

vProxy 호스트의 /etc/hosts에 IP 주소, FQDN, vCenter의 짧은 이름, Data Domain, NetWorker 및 스토리지 노드를 수동으로 추가합니다.

이제 vProxy VM 백업을 시작합니다.
  1. 관리자로 vProxy PuTTY 세션에 로그인한 다음 루트로 전환합니다.
sudo su - root
  1. 다음 명령을 실행하여 /etc/host 항목을 생성합니다.
# echo "IP_of_vCenter FQDN_of_vCenter ShortName_of_vCenter" >> /etc/hosts
샘플: 
# 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
