Testing a parallel global cluster configuration

Symantec recommends testing before putting a global cluster configuration into production.

To test a planned failover

  1. Offline the VCS service group for the database on the cluster at the primary site.
  2. Online the VCS service group for the database on the cluster at the secondary site.

To test distaster recovery at the recovery site

  1. Plan downtime to test the disaster recovery configuration.
  2. Simulate a disaster at the primary site.

    For example:

    Shut down the hosts and storage arrays at the primary. If you can not shut down the storage arrays, disconnect the replication link between the sites.

  3. Use VCS to fail over the database to the cluster at the secondary site.

To test failback on the primary site

  1. Offline the VCS service group for the database on the cluster at the secondary site.
  2. If the nodes and storage are down, restart the nodes and the storage array at the primary site.
  3. Reconnect the replication link if it was broken.
  4. Resynchronize the data from the secondary to make sure the data at the primary site is current.
  5. Bring the VCS service group online at the primary site.
