Actions Performed by the Geographic Edition Software After a Takeover

The following steps occur after you initiate a takeover:

  • If the former primary cluster can be reached and the protection group is not locked for notification handling or some other reason, the protection group is deactivated.

  • The data of the former primary cluster cluster-paris is taken over by the new primary cluster.

    Note -  The data on the former primary cluster cluster-parisC might not be consistent with the data on the original primary cluster. Data replication from the new primary cluster to the former primary cluster is stopped.
  • Application services are brought online on the new primary cluster.

  • The protection group is activated without replication enabled.

For more details about takeover and the effects of the geopg takeover command, see Appendix C, Disaster Recovery Administration Example.
