NDMP backups from EMC Isilon

Attempting to backup an Isilon system using remote NDMP on Netbackup 7.1 (linux media server writing to Datadomain).  We have port 10000 opened bi-directionally between NAS device and media servers. 

When the backup is attempted, it connects and then hangs:

 

06/05/2015 16:30:54 - Info bptm (pid=11360) start
06/05/2015 16:30:55 - Info bptm (pid=11360) using 128 data buffers
06/05/2015 16:30:55 - Info bptm (pid=11360) using 1048576 data buffer size
06/05/2015 16:30:56 - Info bptm (pid=11360) start backup
06/05/2015 16:30:59 - begin writing

 

Are there any other ports that need to be opened?  Anything else I am missing?

 

Thanks,

7.1.x and Earlier

    I'm not sure if this is a issue in this case, but communication between NDMP data server(host to be backed up) and NDMP tape server(media server) should be unlimited.

    I agree with Yasuhisa on this. 

    Your job did not return any failure so it's too early to tell if this is port issue.

    But if you like to understand more about NDMP port requirement, go to:

    I see 'begin writing '. If no data is received by Linux media server, the job will timeout. Do you have bptm log on media server? Logging level of 3 or higher will be needed. Verbose bpbrm log on media server will also tell if file metadata is received.

    Found out that not only does port 10000 need to be opened, but also 1025 - 5000 range from the media to NDMP filer.  After adding this range, the backups are running fine.
