What do I do if the database is not Available.

Initiate a failover

In the Azure portal, browse to the primary database in the geo-replication partnership.

Scroll to Data management, and then select Replicas.

In the Geo replicas list, select the database you want to become the new primary, select the ellipsis, and then select Forced failover.

Select Yes to begin the failover.

Update connection strings

make sure that the connectivity to the new databases is properly configured so that the normal application function can be resumed. This is done in the application configuration file.

Failback to the old primary must be initiated manually

Once the Old Primary is back and available, the switch to make this the primary should be done.
