Reprotecting a Protection Group

Scenarios

After a failback, data is not automatically synchronized from the production site to the disaster recovery site, and protection is disabled for protected instances. To start data synchronization from the production site to the disaster recovery site, reprotect the protection group.

Prerequisites

  • In 24.6.0 or an earlier version, ensure that you have preconfigured the production site servers you want to reprotect according to Configuring Production Site Servers.
  • In 24.9.0 or a later version, SDRS automatically configures the disaster recovery gateway, so you do not need to preconfigure the production site servers before performing a reprotection. In 24.6.0 or an earlier version, ensure that you have upgraded the SDRS software on the gateway and production site servers to 24.9.0 or later and reconfigured the gateway according to Configuring a Disaster Recovery Gateway.
  • The status of protected instances in the protection group is Failback completed or Reprotection failed.

Procedure

  1. Log in to the management console.
  2. Click Service List and choose Storage > Storage Disaster Recovery Service.

    The Storage Disaster Recovery Service page is displayed.

  3. Choose Asynchronous Replication. In the right pane, locate the replica pair housing the protection group you want to reprotect and click the number in the Protection Groups column.

    The Protection Groups tab page is displayed.

  4. In the navigation tree, choose the target protection group.

    The protection group details page is displayed.

  5. In the upper right corner of the basic information area, choose More > Reprotect.

    In 24.9.0 and later versions, SDRS automatically configures the disaster recovery gateway. After a failback, wait for 1 to 2 minutes and then use reprotection.

  6. Select protected instances and click Submit.

  7. The protected instance status changes to Under reprotection. Wait until the operation is complete.

  8. After the operation is complete, the protected instance status changes to Synchronizing, and the amount of data to be synchronized and estimated remaining time are displayed.

    After the failback is successful, disaster recovery site servers will be automatically deleted.
