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. Cohesity recommends that you monitor the Security > Host mappings > Mappings for approval tab for any conflicts that are detected and approve the required mappings.
