    NDMP server ports
    The following list describes the port requirements to backup and restore anNDMP
    server:
    ■ TCP port 10000 must be open from the media server (DMA) to the NDMP filer
    (tape or disk) for all types of NDMP operations; local, remote, and 3-way..
    ■ The NetBackup SERVER_PORT_WINDOW must be open inbound from the
    filer to the media server for remote NDMP and also for efficient catalog file
    (TIR data) movement during local or 3-way NDMP.

     

    You can test the port at OS-level using telnet command.

  • hi,Marianne!

    but,What's the DMA?

    and,What's TCP port must be open from the master server to the NDMP?

     

    THANKS!

    1. The master server talks to the media server using stand ports pbx, vnetd, bpcd, et-cetera.
    2. The media server then talks to the data mover (NDMP filer) on port 10000, so it is from here that you need to try to telnet to the filer on port 10000
    3. If using 3-way NDMP, the filer will connect back to the media server in the range of SERVER_PORT_WINDOW; if lusing local NDMP the filer will write to its locally attached storage device.
    4. During the data transfer from the filer to the storage destination (e.g. local tape drive for local NDMP, media server for 3-way NDMP), the filer will also report the file meta-data (filename, size, permissions, timestamps, ...) back to the Data Managmenet Application (DMA) on the connection opened in step 2.  The media server feeds this info back to the master on the connection opened in step 1.

    The master server does not require access to the NDMP device, only the media server does.  If the same host acts as both master and media then of course the machine you call the master does need access, but that's because one machine is perform two roles.

  • To check NDMP port is opened or not run command

    tpautoconf -probe <NDMP Filer>

    If this command gives you output and notice NDMP Filer details then it confirm the port is opened.
