Results of a Takeover From a Replication Perspective

From a replication perspective, after a successful takeover, the Local-role property of the protection group is changed to reflect the new role, regardless of whether the application could be brought online on the new primary cluster as part of the takeover operation. On cluster-newyork, where the protection group had a Local-role of Secondary, the protection group's Local-role becomes Primary. On cluster-paris, where the protection group had a Local-role of Primary, the following may occur:

• If the cluster can be reached, the protection group's Local-role becomes Secondary.

• If the cluster cannot be reached, the protection group's Local-role remains Primary.

If the takeover is successful, the applications are brought online. You do not need to issue a separate geopg start command

After a successful takeover, data replication between the new primary cluster, cluster-newyork, and the old primary cluster, cluster-paris is stopped. If you want to issue a geopg start command, you must use the -n option to prevent replication from resuming.
