    Hi, I was helping behind the scenes on your support call earlier today. (I recognize the names listed here.) I believe the issue is that a new NDMP host is now the last write host on the tape, but shouldn't be involved in this restore.

    Confirm with

    C:\Program Files\VERITAS\NetBackup\bin\admincmd>nbemmcmd -listmedia -mediaid <mediaid>

    So for this instance we are setting up a 3-way restore and THAT ndmp host informed us which IP addr to give to your RESTORE host which it cannot seem to reach.

    Regardles, if you set the last write host to the media server per the article the above come from, you should be able to do a remote restore.

    https://www.veritas.com/support/en_US/article.TECH68059

    Now further, the ip that the new NDMP host informed of us does not really matter ( as I believe you were unsure where that IP was anyways) as we are less concerned about this new host functionaly to be a host for other filers, I would rather you did the below.

     

    Steps:
    C:\Program Files\VERITAS\NetBackup\bin\admincmd>nbemmcmd -listmedia -mediaid <mediaid>

    Is the new filer listed as last write host on the tape that you are trying to restore from?

    Yes?

    Move it to the media server:

    bpmedia -movedb -m <MEDIA> -oldserver <last write host> -newserver <desired media server for restore>

    The attempt restore once more. Ports for remote NDMP from filer to media server need to be open if any firewalls exits, but IIRC there are none here.

    Hello Nolan,

     

    Last write host is the same media server on which backup was taken for this ndmp. There is no other media server involved.

    Any chance you can show us nbemmcmd output as per mnolan's request? Do you have bprd log that covers failed restore attempt? Please upload as .txt file.
