症状

NetWorker VMware Protection (NVP) 集成已通过 vProxy 设备进行配置。虚拟机 (VM) 备份间歇性地无法使用 hotadd 传输来打开虚拟机的源 VMDK。计划的 VMware 保护工作流执行将在每次执行期间影响不同的虚拟机。

vProxy 备份会话日志显示：

在 vCenter 上运行 100 个虚拟机备份会话，其他虚拟机可能会显示为排队状态。

原因

在计划的 VMware 保护工作流执行期间并发的 hotadd 会话过多。  Dell EMC NetWorker VMware 集成指南中的“性能和可扩展性”部分建议，每台 vCenter Server 的并发备份会话数不超过 100 个。

解决方案

通过移除 vProxies 或更改每个 vProxy 的可用 hotadd 会话，减少在计划的 VMware 保护工作流执行期间并发 hotadd 会话的数量。
