Symptoms

NetWorker VMware Protection (NVP) 整合是透過 vProxy 裝置進行設定。虛擬機器 (VM) 備份間歇性地無法使用 hotadd 傳輸開啟 VM 的來源 VMDK。排定的 VMware 保護工作流程執行會在每次執行時影響不同的 VM。

vCenter 上有 100 個 VM 備份工作階段正在執行，其他 VM 可能會顯示在佇列狀態。

Cause

在執行排定的 VMware 保護工作流程期間，有太多並行的 hotadd 工作階段。  Dell EMC NetWorker VMware Integration 指南中的「效能與擴充能力」一節建議每個 vCenter Server 的並行備份工作階段要少於 100 個。

Resolution

透過移除 vProxy 或變更每個 vProxy 可用的 hotadd 工作階段，在執行排定的 VMware Protection Workflow 期間減少並行 hotadd 工作階段的數量。
