      Verifying a successful fire drill

Verifying a successful fire drill

Run the fire drill routine periodically to verify the application service group can fail over to the remote node.

To verify a successful fire drill

  1. Bring the fire drill service group online on a node at the secondary site that does not have the application running.

    If the fire drill service group comes online, it action validates your disaster recovery configuration. The production service group can fail over to the secondary site in the event of an actual failure (disaster) at the primary site.

  2. If the fire drill service group does not come online, review the VCS engine log for more information.
  3. Take the fire drill offline after its functioning has been validated.

    Failing to take the fire drill offline could cause failures in your environment. For example, if the application service group fails over to the node hosting the fire drill service group, there would be resource conflicts, resulting in both service groups faulting.
