使用SnapMirror迁移SVM后、无法访问CIFS共享
适用场景
- ONTAP 9
- Snapmirror
- CIFS
问题描述
- 在SVM级别迁移之后、用户无法通过灾难恢复集群中的Windows文件资源管理器访问CIFS共享驱动器
- 在Windows端出现以下错误
- [1] 在创建SnapMirror以将所有源Vserver 配置(包括DNS配置)复制到目标Vserver时、Identity保留选项设置为True。
KULNAS1200001::> snapmirror show -destination-path testpath -fields vserver,type,schedule,policy,identity-preserve
source-path destination-path type vserver schedule policy identity-preserve
----------- ---------------- ---- -------- -------- -------------------------------- -----------------
SVMDR: testpath: XDP SVMPDR hourly MirrorAllSnapshotsDiscardNetwork true
- 根据secd日志、确认 DR正在尝试与为主站点设置的DNS服务器进行通信：
