E.4 Testing the Dynamic DNS Solution

After you have created the BCC load scripts for each resource in each of the peer clusters, you are ready to test the overall dynamic DNS solution.

  1. Perform a BCC migrate (failover) of the test resource from the primary cluster to a secondary peer cluster.

    The dynamic DNS script runs before the cluster resource is onlined on the secondary cluster. If everything works correctly, the DNS server should be updated by the time the cluster resource comes online on the secondary cluster.

  2. Test the results of the dynamic DNS update on the secondary cluster by following the step in Section E.2.4, Testing the DNS Server.

  3. Perform a BCC migrate (failback) of the test resource from the secondary peer cluster to the primary cluster.

    The dynamic DNS script runs before the cluster resource is onlined on the primary cluster. If everything works correctly, the DNS server should be updated by the time the cluster resource comes online on the primary cluster.

  4. Test the results of the dynamic DNS update on the primary cluster by following the step in Section E.2.4, Testing the DNS Server.
