Failure during communication with 8.0 or earlier hosts
If insecure communication is not allowed in NetBackup, communication with 8.0 and earlier hosts fails. For successful communication with 8.0 and earlier NetBackup hosts, use one of the following methods:
In the NetBackup Administration Console on the primary server host, select the Settings > Global security > Secure communication > Enable insecure communication with NetBackup 8.0 and earlier hosts option.
On the primary server host, run the following command: nbseccmd -setsecurityconfig -insecurecommunication on.
