适用于

  • ONTAP 9
  • SnapMirror
  • SnapVault
  • 统一复制
  • 存储虚拟机灾难恢复 (SVM DR)
  • VMware Site Recovery Manager (SRM)
  • NetApp 存储复制适配器 (SRA)

问题描述

  • XDP SnapMirror 或 SVM DR 传输所需的时间比预期的要长得多
  • 似乎传输非常缓慢,向目标发送的数据量很少
  • snapmirror show 或者 ActiveIQ System Manager 报告关系状态为 "Preparing" 很长一段时间

ClusterA::> snapmirror show

                    Preparing    98.17GB  true   01/01 12:00:00

  • 卷和 SVMDR 关系在 snapmirror resync 之后都可能经历长时间的 准备 状态
  • 准备操作可能运行时间更长,并且似乎比典型的更新操作传输更多的数据
  • 使用 SRM/SRA 时,VMware 站点恢复期间或站点恢复测试期间的"重新保护"操作需要较长时间或超时
