Context Store provides the option to add or remove Avaya Breeze® platform nodes in the deployed Context Store setup. This feature is only supported in a multi-node cluster. You can add only one node at a time. When you add or remove nodes, ensure that:
No traffic runs through the system
No Geo replication is in operation
Note:
Context Store does not support scaling out dynamically. After adding or removing a node to the cluster, you must shut down all the nodes and start the nodes simultaneously.
The resources of a node must be identical to the other nodes in the cluster. After adding a node and allocating resources to the node, you must manually update the cluster configuration in System Manager before shutting down the nodes. Updating the configuration ensures that the cluster utilizes the new resources.
Note:
When adding or removing nodes, ensure that all external clients that you create or manage are able to handle the changes to capacity or throughput. The maximum requirements for the external clients and connections do not exceed the requirements in the previous Context Store releases. You must provide adequate bandwidth and performance for the external clients.
