    Checking the Status of the Disaster Recovery Configuration

    You check the status of the disaster recovery configuration:

    • After starting the disaster recovery process to ensure that the disaster recovery configuration is accurate, files are being replicated, and the disaster recovery watchdog is monitoring the disaster recovery setup
    • After stopping the disaster recovery process, to ensure that file replication and disaster recovery watchdog process have stopped

    You execute the jmp-dr health command to check the status of the disaster recovery configuration. This command checks the status of asynchronous data replication, file transfer, and disaster recovery watchdog, and the role of clusters in the disaster recovery setup. Errors found during command execution are listed in the command output.

    Note: If you have already executed the jmp-dr health command and the execution is in progress, executing another jmp-dr health command can display incorrect output. The output from the jmp-dr health command also lists whether another instance of the command is being executed.

    To check the status of the disaster recovery configuration at a site:

    1. Log in to the CLI of the Junos Space node at the site on which the VIP or the eth0:0 interface is configured.

      The Junos Space Settings Menu is displayed.

    2. Enter 6 (if you are using a hardware appliance) or 7 (if you are using a virtual appliance) at the Junos Space Settings Menu prompt to run shell commands.

      The following is a sample output from a virtual appliance:
