NDMP Node-scoped mode with BackupExec 2015

Hi All,

I setup FAS2554 switchless cluster and enable NDMP node-scoped mode, the backup software is BackupExec2015.

I can add the Netapp as NDMP server on BackupExec server by using cluster management and backup the volume. However, it cannot backup when the cluster management failover to its partner.

Can anyone give me some hints or guide to configure NDMP with backupexec?

Thanks!!
