Replicating SVM configurations

SVM replication is almost identical to volume replication. Except for specifying how much of the SVM configuration you want to replicate, you can use virtually the same workflow to replicate an SVM as you use to replicate a volume.

See SnapMirror replication workflow.

  • SnapMirror SVM replication workflow
    SnapMirror SVM replication involves creating the destination SVM, creating a replication job schedule, and creating and initializing a SnapMirror relationship.
  • Replicating an entire SVM configuration
    You can use the -identity-preserve true option of the snapmirror create command to replicate an entire SVM configuration.
  • Excluding LIFs and related network settings from SVM replication
    If the source and destination SVMs are in different subnets, you can use the -discard-configs network option of the snapmirror policy create command to exclude LIFs and related network settings from SVM replication.
  • Excluding network, name service, and other settings from SVM replication
    You can use the -identity-preserve false option of the snapmirror create command to replicate only the volumes and security configurations of an SVM. Some protocol and name service settings are also preserved.
  • CIFS only: Creating a CIFS server
    If the source SVM has CIFS configuration, and you chose to set identity-preserve to false , you must create a CIFS server for the destination SVM. CIFS server is required for some CIFS configurations, such as shares during initialization of the SnapMirror relationship.
  • Excluding volumes from SVM replication
    By default, all RW data volumes of the source SVM are replicated. If you do not want to protect all the volumes on the source SVM, you can use the -vserver-dr-protection unprotected option of the volume modify command to exclude volumes from SVM replication.
  • Updating junction paths configured after initialization
    The snapmirror update command will not replicate junction path information added after you create and initialize an SVM replication relationship. You must run snapmirror resync to update the junction path information.
