Service Switchback

Prerequisites

• You have performed reprotection.
• The DR administrator has confirmed that the tenant, through Console, has performed tests and environment clearing for at least once on the recovery plan that requires service migration.

Procedure

1. Log in to the ManageOne OM plane using a browser, click eReplication under Quick Links to log in to eReplication.
   • URL: https://Address for the homepage of the ManageOne OM plane:31943. For example: https://oc.type.com:31943.
   • Default username: admin, default password: Huawei12#$.

   If the login fails, use the following login address and eReplication account and password to log in to eReplication.

   • Login address: https://IP address of eReplication:9443/src/login/view/login.html

     The management plane IP address of an eReplication node can be obtained by querying the IP address of the eReplication_Server01 parameter in the exported LLD.

   • The default account and password are admin and Admin@123, respectively.

2. On eReplication, perform a planned migration.

   This step aims to switch services back to the A (production center) from the B (DR center). After migration, data must be checked. For details, see Step 2 to Step 3 in section Planned Migration of Services in the Production Center.

3. Perform reprotection.

   Replicate data from the A (production center) to the B (DR center) and restore the status of the protected group.

   1. On the menu bar, select Recovery.

   2. Select the recovery plan and click More > Reprotection on the Operation list.
   3. Carefully read the content of the Confirm dialog box that is displayed and click OK to confirm the information.
      • 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.
      • When the protection policy of the recovery plan is Array-Based Replication (Asynchronous), the system forcibly selects Save user configuration data.
   4. In the Operation successful dialog box that is displayed, click OK.
