Phase 1 — Build up the replication partnership between Cluster A and Cluster B

Set up replication between Cluster A and Cluster B.

1. From Cluster A, set up a replication partnership between Cluster A and Cluster B.
2. Create a regular replication schedule so that the target volumes in Cluster B always have an up-to-date replication copy for Cluster A.
   The replication policy must be a one-to-one match on a volume basis, for example:

   Source volume A1 (Cluster A) to target volume B1 (Cluster B)

   Source volume A2 (Cluster A) to target volume B2 (Cluster B)

   NOTE:If NFS exports are used, the NAS volume names of the source and target should be the same, as the export path name includes the NAS volume name. This is not relevant for SMB shares.

   Source volume An (Cluster A) to target volume Bn (Cluster B)

3. Ensure that at least one successful replication has occurred for all the source volumes in Cluster A.

   If the replication fails, fix the problems encountered and restart the replication process.

4. Record all Cluster A settings for future use. Replication restore is not a complete BMR (bare metal restore). Settings such as network configuration (client, SAN, and internal) cannot be backed up and restored using the replication method. Note all Cluster A settings (for use when restoring Cluster A) including network configuration, cluster wide settings such as cluster name, alert settings, and so on for future use. If the system restore operation fails to restore these settings, you can manually restore the Cluster A settings back to their original values.
