We had to configure backup for new NDMP servers. Backups are running fine on the start but then go into pending state at some point with error:
Error Code: [39:501] Description: Client [stpbdedck8s001] was unable to connect to the tape server [swfjdedcba203] on IP(s) [10.100.226.93] port [59022]. Please check the network connectivity. Source: swfjdedcba203, Process: NasBackup

Hello @Emilian
This error happens when connections over ephemeral ports fails. The initial Managmeent connection is successful on port 10000, but then the data connections fail due to us talking to the wrong LIF (via IP address) or because the network ports are restricted.
You can configure a range of ports for us to use and\or setup a Data Interface Pair to make sure we’re talking to the correct IP address for the filer.
