The ServAssure NXT package contains a new playbook for enabling multidatacenter on Cassandra for both the Primary Site (Site A) and the Secondary Failover Site (Site B). It can be found in the /tools/ directory in the extracted NXT-Ansible-$version package. The playbook to execute is cassandra-multi-dc-manager.yml.
To use the new playbook, the following steps are required:
- Edit your "Site A" and "Site B" ServAssure NXT Inventory files and add the required new groups and hosts. Verify that your host_inventory file contains groups and hosts for components included in your deployment. Refer to ServAssure NXT host_inventory file.
- Edit your "Site A" and "Site B" ServAssure NXTsite_vars files and add the required new variables. Verify that your site_vars file contains parameters and variables for components and features included in your deployment. Refer to ServAssure NXT site_vars file.
