A cluster administrator can create a Storage Virtual Machine (SVM) peer relationship to provide an authorization infrastructure for running SVM peering applications between two SVMs by using the vserver peer create command. You can create an SVM peer relationship between two SVMs either in a single cluster (intracluster) or in peered clusters (intercluster).
Before you begin
- If you want to create an intercluster SVM
peer relationship, you must have ensured that both the clusters are peered with each other.
- The names of the SVMs in the peered clusters must be unique across the clusters to be peered and any other clusters with which either of the clusters are individually peered.
If the SVMs do not have unique names, you must rename
one of the SVMs by using the vserver rename command.
For example, consider two clusters, cluster A and cluster B, that are peered with cluster C. Clusters A and cluster B must not have SVMs with identical names even though cluster A and cluster B are not peered. You must rename one of the SVMs, if there are SVMs with identical names.
- The admin state of the SVMs to be peered must not be in initializing or deleting state.
- If any previously attempted SVM peer relationship between the same SVMs is in the rejected state, you must have deleted these SVM peer relationships.
About this task
- Peered clusters can be managed by a single cluster administrator or different cluster administrators.
- You can specify the applications that will communicate over the peer relationship when you create an SVM peer relationship.
If you do not specify the application for the peer relationship, such as snapmirror, an SVM administrator cannot perform operations related to the applications between the peered SVMs.
- For SVMs with FlexVol volumes, you can create intercluster and intracluster SVM peer relationships.
- For SVMs with Infinite Volume, you can create only intercluster SVM peer relationships.
- You cannot create an SVM peer relationship between SVMs with FlexVol volumes and SVMs with Infinite Volume.
- You can create multiple SVM peer relationships simultaneously either by using different SSH sessions or by using a script.
Note: It is best to create not more than five SVM peer relationships simultaneously to avoid any performance degradation.
