Can I use SVM-DR in a cascade configuration?
Applies to
- SnapMirror
- ONTAP 9
- ONTAP 9.1
- ONTAP 9.2
- Data ONTAP Simulator
- ONTAP 9.3
Answer
No, SVM-DR is designed to be used in an A --> B configuration. Type DP and XDP SVM-DR require the source SVM of the transfer to contain subtype 'default'.
Scenario:
- A --> B --> C
(A) Production Cluster: cluster-a
(A) Production SVM: production
--Mirrored/Type: DP--
(B) DR Cluster: cluster-b
(B) DR SVM: secondary
--Proposed vault/Type: XDP--
(C) Vault Cluster: cluster-c
(C) Vault SVM: tertiary
- A --> B are Mirrored using Type: DP
cluster-b::> snapmirror show
Progress
Source Destination Mirror Relationship Total Last
Path Type Path State Status Progress Healthy Updated
----------- ---- ------------ ------- -------------- --------- ------- --------
production: DP secondary: Snapmirrored
Idle - true -
When a SnapMirror create is attempted for 'secondary:' to 'tertiary:' on cluster-c, the following error displays:
cluster-c::> snapmirror create -source-path secondary: -destination-path tertiary: -type XDP
Error: command failed: Vserver "secondary" is not a Vserver of subtype "default".
