Add secondary data network operation does not fail on the secondary site if the same NetBackup primary IP/FQDN is used to add the secondary data network in both the primary and secondary site
On a NetBackup Flex cluster configured with disaster recovery, you are not allowed to use the same IP/FQDN to add a secondary data network in both the primary and secondary site. But in the GUI, if you add a secondary data network in the secondary site using the same NetBackup primary IP/FQDN that was used to add the secondary data network in the primary site, the operation is successful. But if you perform disaster recovery takeover operation, the operation fails as the IP is already online on the primary site.
