This appendix provides details about the state of the primary and secondary clusters after a geopg takeover command is executed.
This appendix contains the following topics:
Results of a Takeover When the Partner Cluster Can Be Reached
Results of a Takeover When the Partner Cluster Cannot Be Reached
This section describes the activation state of the primary and secondary clusters before and after a geopg takeover command is executed. The results described in this section assume that the partner cluster can be reached
The following table describes the states when the geopg takeover command is executed on the secondary cluster, cluster-newyork.
Table C–1 Takeover Results When geopg takeover Is Executed on the Secondary Cluster
Cluster Role and State Before Takeover |
Cluster Role and State After Takeover |
---|---|
cluster-paris: primary, deactivated cluster-newyork: secondary, deactivated |
cluster-paris: secondary, deactivated cluster-newyork: primary, deactivated |
cluster-paris: primary, activated cluster-newyork: secondary, deactivated |
cluster-paris: secondary, deactivated cluster-newyork: primary, deactivated |

cluster-paris: secondary, deactivated cluster-newyork: primary, activated, with data replication stopped |
The following table describes the states when the geopg takeover command is executed on the primary cluster, cluster-paris.

This section describes the activation state of the primary and secondary clusters before and after a geopg takeover command is issued when the partner cluster cannot be reached or when the protection group on the partner cluster is busy.
The following table describes the states when the geopg takeover command is issued on the secondary cluster, cluster-newyork, and the primary cluster cannot be reached or the protection group on the primary cluster is busy.
The cluster role and state after the takeover, which is given in the table, is only available when the partner cluster can once more be reached.

Cluster Role and State After Takeover |

The following table describes the states when the geopg takeover command is executed on the primary cluster, cluster-paris, and the secondary cluster cannot be reached or the protection group on the secondary cluster is buy.
