NetWorker：vProxy 備份失敗，傳回「Unable to backup virtual disk "Hard disk 1"」

NetWorker VMware Protection 整合是透過 vProxy 裝置進行設定。無法在環境中完成虛擬機器備份。NetWorker Management Console 訊息指出它是 unable to backup virtual disk "Hard disk 1."

若要移除附加至 vProxy 的額外磁碟，請參閱 LKB00022590 NVP-vProxy：如何在 vProxy 應用裝置上使用執行狀況檢查工具 ProxyHC。

vProxy vbackupd-engine.log 檔案和 NetWorker 伺服器備份記錄顯示：

vProxy 無法使用連接埠 902 連線至目標 ESXi 主機。vProxy 備份工作流程會使用 VMware Virtual Disk Development Kit （VDDK） 命令連線至 vmdk 檔案，使用以下方法： hotadd 或 nbd，以執行備份。

請確定 vProxy 可以使用所需的連接埠 （443 和 902） 連線至 ESXi 主機。Dell NetWorker 與 VMware 整合指南中的 「連接埠需求」 表格包含解決方案所需連接埠的詳細資料和最新資訊。
