Example 2- Setting up Bunker replication

Last published : Jul 07, 2026
You can choose to add the Bunker node either after the Primary RVG has been created or after the RDS with the Primary and Secondary RVG is created. You can add a Bunker to an existing RDS without interrupting replication from the Primary to the Secondary.
To create and add the Bunker RVG to an RDS with Primary and Secondary RVG
  1. On the Bunker node VVRBunker, create a new disk group, vvrdg, containing the volume that is intended to be used as the Replicator Log.
  2. On the Primary node VVRPRI, create and add the Bunker using the command:
    vxrds -g vvrdg addBunker vvrrvg VVRPRI VVRBunker
    where, vvrrvg is the RVG name; VVRPRI is the Primary; VVRBunker is the Bunker node.
    This command creates RLINKs between the Bunker and the Primary, and also between the Bunker and each Secondary in the RDS.
    To create and add the Bunker RVG to an RDS that consists of only the Primary RVG
    1. On the Bunker node VVRBunker, create a new disk group, vvrdg, containing the volume, rep_log_vol intended to be used as the Replicator Log.
    2. On the Primary node VVRPRI, create and add the Bunker using the command:
    vxrds -g vvrdg addBunker vvrrvg VVRPRI VVRBunker
where, vvrrvg is the RVG name; VVRPRI is the Primary name; VVRBunker is the Bunker node name.
  1. Create a Secondary RVG with the same name as the Primary RVG and add it to the RDS.
    vxrds -g vvrdg addsec vvrrvg VVRPRI VVRSEC
    1. Attach the Secondary RLINKs and start replication on the Primary using the command:
    vxrlink -g vvrdg -a startrep vvr_rvg rlk_vvrsec
To add multiple Bunker hosts refer to the following sections:
