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 to 8.1.
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.
