The RL can become invalid in the scenario below, as shown:
If we wish to do a Failback after a planned failover, we cannot use the current RL since there is no room left on the Replication log and it would be in an invalid condition. We can delete the section to free up space on RL and reuse it.
In the case of Resuming Continuous Rehydration operation, existing RL will be useful or else we can delete the section to repurpose it.
Explanation: The Replication Log on the protection site will no longer be in use and will become invalid when we do a failover, and the DRVA on the failover site will take ownership of the domain.
The replication log will maintain a record of data being replicated to the object store.
In the below image, we can see the RL has become invalid.
In the below screenshot, we can see an option to delete the section on a Replication log.
