The dmcluster config command sets up SSH connections between the DM1, DM2, DM3, VP1, and VP2 servers. These connections are used by the Data Mover monitoring service to monitor the designated-active Data Mover components and initiate a failover if any of the designated-active components stop working.
  1. On the designated-active (DM1) server, enter the following changes to the failover.properties file:
    • local.daemon.host=DM1
    • remote.daemon.host=DM2
    • local.monitor.host=VP1
    • remote.monitor.host=VP2
    • local.repository.host=DM1
    • remote.repository.host=DM2
    • local.agents.host=DM1, DM2, DM3
    • remote.agents.host=DM1, DM2, DM3
  2. Run ./dmcluster config as root and follow the following prompts:
