CG 中的卷离线是否会影响SnapMirror主动同步？
适用于
- SnapMirror活动同步
- 一致性组 (CG)
- ONTAP 9.10.1 及更高版本
问题解答
是的，因为SnapMirror主动同步是一种实时同步关系，卷脱机将中断卷的同步，并最终导致关系不同步。因此，关系中的所有卷 (CG) 都会受到影响。
附加信息
当卷脱机时，将出现警告消息和不同步事件：
cluster1::*> vol offline -volume sql1_dbWarning: 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}: yVolume "svm1_cluster1:sql1_db" is now offline.不同步事件：
