vProxy 主机级别的名称解析问题

Resolución

在 vProxy 主机的 /etc/hosts 中手动添加 vCenter、Data Domain、NetWorker 和存储节点的 IP 地址、FQDN、短名称。

立即启动 vProxy 虚拟机备份。
  1. 以管理员身份登录 vProxy PuTTY 会话，然后切换到 root：
sudo su - root
  1. 运行以下命令以创建 /etc/host 条目
# echo "IP_of_vCenter FQDN_of_vCenter ShortName_of_vCenter" >> /etc/hosts
样品： 
# 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
