適用対象

  • SnapMirrorアクティブ同期
  • コンシステンシグループ(CG)
  • ONTAP 9.10.1以降のバージョン

回答

はいSnapMirror Active Syncはリアルタイム同期関係であるため、ボリュームがオフラインになるとボリュームの同期が中断され、関係が確実に同期されなくなります。したがって、関係(CG)内のすべてのボリュームに影響します。

追加情報

ボリュームがオフラインになると、警告メッセージが表示され、同期が取れなくなるイベントが発生します。
cluster1::*> vol offline -volume sql1_db
Warning: Volume "sql1_db" in Vserver "svm1_cluster1" is currently part of a SnapMirror Synchronous relationship. Taking the volume offline operation will disrupt the zero RPO protection.
Do you want to continue? {y|n}: y
Volume "svm1_cluster1:sql1_db" is now offline.
