About NetBackup clients installed on nodes of a clustered application

Review the following scenarios about secure communication with NetBackup clients installed on nodes of a clustered application:

  • For successful communication, you need to simultaneously upgrade all cluster nodes.

  • Ensure that the virtual name is mapped to all cluster nodes to avoid backup failures after a failover. Veritas recommends that you monitor the Security Management > Host Management > Mappings for approval tab for any conflicts that are detected and approve the required mappings.
