This example shows how to fail back to the original Primary seattle using the difference-based synchronization feature, in an RDS with multiple Secondaries.
To fail back to the original Primary using difference-based synchronization in a setup with multiple Secondaries
See Example - Failing back to the original Primary using difference-based synchronization.
On the original Primary seattle:
Synchronize the data volumes in the Secondary RVG hr_rvg on tokyo with the data volumes in the original Primary RVG hr_rvg using the difference-based synchronization and Storage Checkpoint. To do this, use the following command on any host in the RDS:
# vradmin -g hrdg -c checkpt syncrvg hr_rvg tokyo
The -c option when used with the vradmin syncrvg command automatically starts a Storage Checkpoint with the specified name, checkpt, in this example. After the data volumes are synchronized, the Storage Checkpoint is ended.
Start replication from seattle to tokyo using the command:
# vradmin -g hrdg -c checkpt startrep hr_rvg tokyo
