Takeover Postconditions
This appendix provides details about the state of the primary and secondary clusters after you
run the geopg takeover command or the geomg takeover
command.
This appendix contains the following sections:
Results of a Takeover When the Partner Cluster Can Be Reached
This section describes the activation state of the primary and secondary clusters before and
after you run the geopg takeover command. The results described in this section
assume that the partner cluster can be reached.
The following table describes the states of the clusters when you run the geopg
takeover command on the secondary cluster, cluster-newyork.

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 you run a geopg takeover command 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 you run the geopg takeover
command on the secondary cluster, cluster-newyork, and the primary cluster cannot
be reached or the protection group on the primary cluster is busy.
Note -
The cluster role and state after the takeover, which is given in the table, is available only
when the partner cluster can be reached again.
