Replacing the recovery appliance

Follow these steps to prepare the new recovery appliance to take its place in the disaster recovery configuration.

About this task

To prepare the new recovery appliance you power up the new appliance and configure the Ethernet ports as they were configured for the original recovery appliance.

You then work on the main appliance to create the queue managers as primary instances in the new disaster recovery configuration. You run the commands produced by that procedure on the recovery appliance to create secondary instances of the queue managers and synchronize them with the primary instance.

Procedure

  1. Remove the existing recovery appliance from the network and power it down.
  2. Power up the new recovery appliance and attach the supplied serial console cable to the console port.
  3. Configure the ETH20 port. This is the port over which you will connect to the main appliance. See Configuring Ethernet interfaces by using the command line for help with configuring the Ethernet ports.
    Note: If you set up your original DR configuration to use a custom interface for replication, then you should use the same interface for your new appliance. See Configuring custom DR replication interfaces.
  4. Configure the MGT0 port with the same details that the appliance you are replacing was configured. (This connection enables you to send commands to the appliance from a remote workstation.)
  5. Configure the remaining Ethernet ports as they were originally configured for the recovery appliance.
  6. Connect the ETH20 port to the 10 Gb network that the ETH20 port of the recovery appliance is connected to.
  7. Connect the MGT0 port to the 1 Gb network that the MGT0 port of the recovery port is connect to.
  8. Ping the main appliance to check the connections.
  9. Make other network connections as required to replicate the configuration of the original recovery appliance.
  10. On the main appliance, complete the following steps:
    1. Enter MQ administration mode by typing mqcli on the command line.
    2. Enter the following command: 
      crtdrprimary -m queue_manager_name -r new_appliance_name -i new_appliance_IP 
-p port
      On successful completion, the command outputs a crtdrsecondary command.
    3. Restart the queue manager: 
      strmqm queue_manager_name
  11. On the recovery appliance, complete the following steps:
    1. Enter MQ administration mode by typing mqcli on the command line.
    2. Enter the crtdrsecondary command, exactly as output in step 10b. Synchronization of data from the main appliance to the recovery appliance begins.
    3. Check the progress of the synchronization by using the status command. 
      status queue_manager_name
  12. Repeat steps 10 and 11 for each queue manager.
