Veritas NetBackup™ Deduplication Guide

License information failure during MSDP configuration

A configuration error message about license information failure indicates that the NetBackup servers cannot communicate with each other.

If you cannot configure a deduplication storage server or load balancing servers, your network environment may not be configured for DNS reverse name lookup.

You can edit the hosts file on the media servers that you use for deduplication. Alternatively, you can configure NetBackup so it does not use reverse name lookup.

To prohibit reverse host name lookup by using the Administration Console

  1. In the NetBackup Administration Console, expand NetBackup Management > Host Properties > Master Servers.
  2. In the details pane, select the master server.
  3. On the Actions menu, select Properties.
  4. In the Master Server Properties dialog box, select the Network Settings properties.
  5. Select one of the following options:

    • Allowed

    • Restricted

    • Prohibited

    For a description of these options, see the NetBackup online Help or the administrator's guide.

To prohibit reverse host name lookup by using the bpsetconfig command

  • Enter the following command on each media server that you use for deduplication:

    echo REVERSE_NAME_LOOKUP = PROHIBITED | bpsetconfig -h host_name

    The bpsetconfig command resides in the following directories:

    UNIX: /usr/openv/netbackup/bin/admincmd

    Windows: install_path\Veritas\NetBackup\bin\admincmd
