Configuring SVM-scoped NDMP

If the DMA supports the Cluster Aware Backup (CAB) extension, you can back up all the volumes hosted across different nodes in a cluster by enabling SVM-scoped NDMP, configuring a backup user account, and configuring LIFs for data and control connection.

Before you begin

The CAB extension must be supported by the DMA.

  1. Enabling SVM-scoped NDMP on the cluster
    You can configure SVM-scoped NDMP on the cluster by enabling SVM-scoped NDMP mode and NDMP service on the cluster (admin SVM).
  2. Configuring a backup user for the cluster
    To authenticate NDMP from the backup application, you must create a local backup user, or an NIS or LDAP user for the cluster with the admin or backup role, and generate an NDMP password for the backup user.
  3. Configuring LIFs
    You must identify the LIFs that will be used for establishing a data connection between the data and tape resources, and for control connection between the admin SVM and the backup application. After identifying the LIFs, you must verify that firewall and failover policies are set for the LIFs, and specify the preferred interface role.
