适用场景

  • DP
  • Snapmirror

问题描述

  • 在Azure中部署了一个新的CVO系统、并尝试实施以下SnapMirror级联：
站点A (生产)到站点B (Azure CVO1)再到站点C (Azure中的新CVO)。
 
  • 已对卷执行站点A到站点B的复制并进行了快照镜像。
 
  • 在站点C上创建了一个新卷、但在尝试使用命令行界面创建从站点B到站点C的级联关系时、
此时将创建此关系、但镜像状态在System Manager中显示为已断开、而不是未初始化。
 
  • 唯一可用的选项是重新同步、此操作将失败并显示以下错误：
 
"Transition to snapmirrored state failed. Reason: No common Snapshot copy found between
svm_b:vol_mir and svm_c:vol_mir".
 
  • 目标是通过SnapMirror将卷从站点B复制到站点C、以便最终用户可以停用站点B并恢复从站点A到站点C的复制
