ONTAP 9
SnapMirror 活动同步(SM-AS)/ SnapMirror业务连续性(SM-BC)

问题描述

SnapMirror同步报告了高延迟
- SM-A/SM-BC依赖于同步SnapMirror (SM-S)
- 命令行界面命令qos statistics workload latency show 显示了中的高延迟SM Sync
- AIQUM/OCUM 显示了中的高延迟 Sync SnapMirror
主站点上记录EMS错误：

Tue Apr 04 02:38:22 +0800 [Node1-01: repl_Handle_sync_resl: callhome.syncsm.exception:error]: Call home for SNAPMIRROR SYNCHRONOUS EXCEPTION: Network Latency exceeded threshold limit.

命令行界面命令network test-link 显示源集群和目标集群之间的网络延迟较长
