If planned migration or fault recovery has been performed for a recovery plan, you can execute reprotection for the recovery plan. Reprotection protects data at the original disaster recovery (DR) site once devices at the original production site recover from disasters, simplifying failback.
Prerequisites
If reprotection needs to be performed after fault recovery, clear the environment of the original primary end and the recover replications of the original DR site switch to production site before performing other operations.
- You have logged in to the eReplication as a user with DR management permission.
- Planned migration or fault recovery has been performed for at least one recovery plan on eReplication.
- Before performing reprotection, check whether protected groups at the original production site are in the Invalid state.
- Before reprotection, underlying storage links, remote replications, and consistency groups have been recovered.
Context
In order to ensure the previous configuration does not effect the execution of protected group and recovery plan, the system will automatically clear protection and recovery configuration (includes the protected policy, startup setting for recovery plan, self-defined execution script and execution steps) . Please re-configure protected policy and recovery policy after you execute reprotection to ensure the normal operation of DR services.
- If the recovery plan is based on the snapshot or clone protection policy template, reprotection cannot be performed.
- Reprotection is not supported in the following scenarios:
- In solutions based cascading replication (synchronous and asynchronous) or parallel replication (synchronous and asynchronous), services switched to the remote DR site do not support reprotection.
- In solutions based on cascading replication (asynchronous and asynchronous), services switched to the remote DR site do not support reprotection.
Procedure
- On the menu bar, select Utilization > Data Restore.
- Select the remote recovery plan for which you want to execute reprotection and click More > Reprotection on the Operation list.
- In the Warning dialog box that is displayed, read the content of the dialog box carefully and click OK.
If Save user configuration data is selected, self-defined protection policies and recovery settings, such as self-defined recovery steps, will be retained. Ensure that the configuration data has no adverse impact on service running after reprotection.
Result
- After the reprotection starts, you can view the execution process and result. If the task is failed, you can solve the problem and execute the task again.
- After the reprotection, it protects data at the original DR site once devices at the original production site recover from disasters, the original DR site is production site.
