Fault Recovery of the Remote DR Center (Parallel Network)

When reconstructing the remote DR center on a parallel network, you need to restore synchronous remote replication, add and refresh site resources, and create new protected groups and recovery plans.

Prerequisites

Physical and logical links have been ready between the remote DR center and the production center.
The configurations of LUNs are the same on the storage arrays in the remote DR center and the production center.

Procedure

Log in to the storage array in the production center and create asynchronous remote replication from the production center to the remote DR center.
Synchronize data for consistency groups of asynchronous remote replication.
Log in to the eReplication DR management server in the remote DR center and add new hosts and storage arrays to the corresponding sites.
Log in to the eReplication DR management server in the same-city DR center and refresh site resources in the remote DR center.
Delete invalid protected groups and recovery plans.
Re-create related protected groups and recovery plans.

Result

Asynchronous remote replication is restored between storage arrays in the production center and the remote DR center.
protected groups are restored based on the DR plan. You can see a clear and complete DR topology and perform DR testing.
