Exchanging the DR Direction
In dual-active DR, only forward tasks support DDL execution to prevent DDL loopback. DRS allows you to exchange the direction of a DR task. You can use this function to change the task role to enable DDL execution on backward tasks.
Constraints
- This function is available only for dual-active DR tasks.
- The direction can be exchanged only when both the forward and backward tasks are paused.
- You need to resume the task to apply the change.
Procedure
- On the Disaster Recovery Management page, locate the paused dual-active DR task.
Subtask 1 is a forward task.
View the DR monitoring of subtask 1. The DDL execution is disabled on active node 2.
- Click Exchange Direction in the Operation column of the task.
- In the displayed dialog box, click Yes.
- After the direction exchange, view that the DR relationship of subtask 1 changes and subtask 1 becomes a backward task.
View the DR monitoring of subtask 1. The DDL execution is disabled on active node 1.
- Click Resume in the Operation column of the subtask.
