After a partial or full DR switchover, when there are additions and changes to the databases, restore Unified Collaboration Administration (UCA) and Unified Collaboration Model (UCM) data. If the customer does not require any data from DC2 to be restored, do not uninstall or reboot the cluster.
Procedure
Log on to Avaya Aura® System Manager.
On the System Manager web console, click Elements > Avaya Breeze® > Configuration > Attributes.
On the Service Clusters tab, select UCAStoreService.
In the Startup Configuration group, set the Disaster recovery role attribute to GEO_MASTER on DC1 and GEO_SLAVE on DC2.
Important:
Disaster recovery role is a mandatory attribute if you require geographical disaster recovery. After configuration, if you change the Disaster recovery role attribute, you must reboot the cluster for the changes to take effect.
