NetWorker：vProxy 备份失败，并显示“Unable to backup virtual disk "Hard disk 1”（无法备份虚拟磁盘“硬盘 1”）

NetWorker VMware 保护集成配置了 vProxy Appliance。虚拟机的备份无法在环境中完成。NetWorker Management Console 消息指示它是 unable to backup virtual disk "Hard disk 1."

要删除附加到 vProxy 的额外磁盘，请参阅 LKB00022590 NVP-vProxy：如何在 vProxy 设备上使用运行状况检查工具 ProxyHC。

vProxy 无法使用端口 902 连接到目标 ESXi 主机。vProxy 备份工作流使用 VMware Virtual Disk Development Kit （VDDK） 命令连接到 vmdk 文件，使用： hotadd 或 nbd，以便执行备份。

确保 vProxy 可以使用所需的端口（443 和 902）连接到 ESXi 主机。Dell NetWorker 和 VMware 集成指南中的 “端口要求” 表包含有关解决方案所需端口的详细信息和最新信息。
