About adding license keys
If you add other licenses at the end of a Windows master server installation, then you must failover and add these licenses to each node in the cluster. If you add new licenses later, you also need to failover to add these licenses to each node in the cluster. On Windows, you can also use the bpminlicense command. On UNIX/Linux servers, you can alternatively use the get_license command to add license keys without having to failover to each node.
Some features and products (such as NetBackup Shared Storage Option) require the keys to also be installed on the media server.
