适用场景

  • ONTAP 存储复制适配器

问题描述

Storage Repliation Adapter (SRA)可通过 SyncOnce  操作对受保护卷执行SnapMirror更新。  SyncOnce 此操作会在以下SRM工作流中触发:

  • 测试故障转移
  • 计划内迁移

在具有大量SnapMirror关系的某些环境中、可以看到以下问题描述:

  • SyncOn一次 操作失败、并显示"未知"错误。  此错误的错误代码为4001
  • 查看vvolvp.log中的操作时:
    • 实际上、SnapMirror更新可能会成功:
      • 2023-07-06T00:39:30,352Z (DEBUG)[pool-3-thread-1] [] updateSnapMirror:
        2023-07-06T00:39:30,352Z (DEBUG)[pool-3-thread-1] [] Sending-1861: <snapmirror-update><destination-location>volume</destination-location><source-location>volume</source-location></snapmirror-update>

        2023-07-06T00:39:31,135Z (DEBUG)[pool-3-thread-1] [] SnapMirror update returned status succeeded
    • 但是 snapmirror-get-iter 、SnapMirror更新之后会发生一个API调用、该调用会超时:
      • 2023-07-06T00:39:31,635Z (DEBUG)[pool-3-thread-1] [] Sending-1862:<snapmirror-get-iter><max-records>500</max-records><query><snapmirror-info><relationship-group-type>none</relationship-group-type></snapmirror-info></query></snapmirror-get-iter>
