About Fire Drill Wizard general operations
The Fire Drill Wizard performs the following operations:
Prepares for the fire drill by creating a fire drill service group on the secondary site
The fire drill service group is a copy of the application service group. When creating the fire drill service group, the wizard uses the application service group name, with the suffix _fd. The wizard renames the fire drill service group resources by adding a prefix FDnn and changes attribute values as necessary to refer to the FD resources.
The wizard also supports fire drill service groups created under a different naming convention by an earlier version of the wizard.
Runs the fire drill by bringing the fire drill service group online on the secondary site
This operation demonstrates the ability of the application service group to failover and come online at the secondary site should the need arise.
Fire drill service groups do not interact with outside clients or with other instances of resources, so they can safely come online even when the application service group is online on the primary site.
Restores the fire drill configuration, taking the fire drill service group offline
After you complete a fire drill, run the wizard to restore the fire drill configuration to a prepared state. Otherwise, the fire drill service group remains online.
If you run a fire drill on one service group, restore that service group before you continue with a fire drill on another service group.
You must also restore the fire drill configuration before you can delete it.
Warning:
If the fire drill service group remains online, it could cause failures in your environment. For example, if the application service group were to fail over to the node hosting the fire drill service group, there would be resource conflicts, resulting in both service groups faulting. Therefore, after completing the fire drill testing for a service group, always use the wizard to restore the fire drill configuration to a prepared state as soon as possible.
Deletes the fire drill configuration
The details of some Fire Drill Wizard operations are different depending on the replication environment.
