NetBackup™ Flex Scale Administrator's Guide

Configuring an external BYOS media server

You can configure an external BYOS media server (EMS) with NetBackup Flex Scale.

If you have an external media server writing to NetBackup Flex Scale storage server:

  • Add the external media server to list of media servers who can write to that storage server.

  • Do not use Allow NetBackup to automatically select option when selecting the media server. You must explicitly specify the list of media servers to be used.

  • When you add a new node (which adds a new media server), you must add that media server explicitly.

To configure an external BYOS media server with NetBackup Flex Scale

  1. Deploy mapping BYO on the external media server.
    • Enter the NetBackup Flex Scale primary server details.

    • Enter the token that you get from the primary server.

  2. Go to Host Properties > Primary Server > Servers > Additional server tab. Add an entry for the external media server on the primary server.
  3. Go to Host Properties > Media Server > Servers -> Additional server tab. Add an entry for the external media server (all media cluster nodes).
  4. Go to Host Properties > Clients > Servers > Additional server tab. Add an entry for the external media server on the client server.
  5. Go to /usr/openv/netbackup/bin/admincmd/ and run the following command:
    # ./nbemmcmd -addhost -machinename ems_fqdn -machinetype 
    media -primaryserver primary_server_fqdn -operatingsystem 
    Linux -netbackupversion 10.0
    NBEMMCMD, Version: 10.0 
    Command completed successfully.

    where ems_fqdn is the external media server FQDN and primary_server_fqdn is the primary server FQDN.

  6. Restart the EMS server services.
  7. Perform a robot inventory. Go to Configure Storage devices and confirm that the external media server is detected.

    To perform a robot inventory, refer to the Veritas NetBackup™ Administrator's Guide, Volume I.

If you have configured disaster recovery and want to configure an external media server, then perform the following steps:

  • Clear the host cache on the primary server node

    bpclntcmd -clear_host_cache
  • Check for the correct IP resolved by EMS after disaster recovery is configured:

    # bptestnetconn
    # bptestbpcd -M primary FQDN
    # bpclntcmd -hn primary FQDN
  • After clearing the host cache, bptestnetconn paramenter should not show the entry, Stale entry message for EMS server.
