Last Updated : May 30, 2024 |

About this task

You can restore a node in an Avaya Hybrid Cloud Gateway cluster by reinstalling the node with the same IP address and Fully Qualified Domain Name (FQDN). The re-installation process synchronizes the data and configuration from the other nodes in the cluster.

Note:

This topic is not applicable if you upgrade Avaya Hybrid Cloud Gateway to version 1.0.5 or later. For guidance, contact Avaya Cloud Operations.

Before you begin

Ensure that the Avaya Hybrid Cloud Gateway software and the backup are the same version.

Procedure

  1. To uninstall the existing node, run the following command: app uninstall
  2. To reinstall the same version of the Avaya Hybrid Cloud Gateway software as the backup, do the following:
    1. To re-image the nodes, redeploy the Open Virtualization Appliance (OVA).
    2. To install Avaya Hybrid Cloud Gateway, run the following commands:

      • chmod 770 AHCG-<version>.bin

      • app install AHCG-<version>.bin

    3. On the Initial Installation Configuration page, select Cluster Configuration.
    4. On the Clustering page, set Initial Cluster Node as n (No).
    5. On the Clustering page, enter the IP address of the cluster seed node.

      Use the same keystore and database password that you used while installing the initial cluster setup.

      Avaya Hybrid Cloud Gateway is installed with the basic load.
