Disaster Recovery at a Mirror Grid

This procedure is used when the primary grid is unavailable and you want to run the cutover.

Procedure

If the primary grid's realm service is down, stop the remaining satellite realm services.
Select a new data grid that is going to be the primary grid. Restart the realm service of the new primary grid as the "primary" realm service by omitting the satelliteof configuration option. If there are additional mirror grids, restart their realm services as "satellite" realm services, by specifying the satelliteof configuration option and referencing the new "primary" realm service.
Use the following command to activate the mirror grid to be the new primary grid.
```
