DPM 2010 and Backup lan issues RRS feed

  • Question

  • Hi

    I have searched quite some forum's, but didn't find any answer.

    I want to implement a backup lan with dpm 2010.

    Each machine has 2 network interfaces: Production: 10.176.28.0/16 and backup Lan 172.17.28.0/16.

    Without configuration, the backup lan isn't used.

    Next I defined all entries in the hosts file:

    DPM SERVER hosts file

    -----
    172.17.28.1  VM1
    172.17.28.1  VM1.<fqdn>
    172.17.28.2  VM2
    172.17.28.2  VM2.<fqdn>
    -----

    VM hosts file

    -----
    172.17.28.200  DPM
    172.17.28.200  DPM.<fqdn>
    -----

    This works but is quite unamangeable.

    Next I wanted to define a backup lan via the add-backupnetworkaddress:

    add-backupnetworkaddress -dpmservername DPM -address 172.17.28.0/16 -sequencenumber 1

    as from this moment consistency checks and backups failed. It seems like it doesn't get up to speed.(with or without the entries in the hosts file)

    Each time I changed something I rebooted the dpm server and restarted the dpm agents.

    If I add the backup network and analyze the traffic everything passes through the production network instead of the backup lan.

    I'm quite clueless here how to proceed to use the backup lan in an "easy" way.

  • when you setup hosts the backup via backup lan worked?

  • Indeed, when I use the hosts file everything works just fine, only it is a big hassle to maintain if you have 200+ servers.

    I you have any tips how to troubleshoot, they are always welcome.

  • Yes,

    That's the only way I know you can make this to work...

  • Thanks for the info.

    I only wonder what the add-backupnetworkaddress does then, and moreover why it doens't work at all when I define it.
    Whats the point then of the add-backupnetworkaddress command at all?
