Tasks for configuring and running fire drills
While running the Fire Drill Wizard, the following sequence of actions are available:
Prepare the fire drill configuration
Run the fire drill or delete the configuration
Restore the fire drill configuration after running a fire drill
Run another fire drill or delete the configuration
In addition, you have the option to re-create a fire drill configuration that has changed.
After an action is complete, the next action becomes available in the wizard. You can select the next action or exit the wizard and perform the next action later.
The following table gives more details of the process of configuring and running fire drills with the wizard.
Table: Tasks for configuring and running fire drills
Action | Description |
---|---|
Verify the hardware and software prerequisites | Before running the wizard, review the prerequisites and make sure that they are met. |
Prepare the fire drill configuration | Use the wizard to configure the fire drill. |
Re-create a fire drill configuration that has changed | If a fire drill configuration exists for the selected service group, the wizard checks for differences between the fire drill service group and the application service group. If differences are found, the wizard can re-create the fire drill configuration before running the fire drill. See Re-creating a fire drill configuration that has changed. |
Run the fire drill | Use the wizard to run the fire drill. Running the fire drill brings the fire drill service group online. Optionally you can specify a script to be run once the fire drill is complete. See Running a fire drill. Perform your own tests of the application to confirm that it is operational. Note: After completing the fire drill testing, run the wizard again as soon as possible to restore the configuration. Otherwise the fire drill service groups remain online. It is recommended that you restore a fire drill service group to a prepared state before running a fire drill on another service group. |
Restore the fire drill configuration to a prepared state | Use the wizard to restore the fire drill system to a state of readiness for future fire drills or to prepare for removal of the fire drill configuration. This is a required action after running the fire drill. See Restoring the fire drill system to a prepared state. This operation takes the fire drill service group offline and reattaches snapshot mirrors. |
Delete the fire drill configuration | If a fire drill service group is no longer needed, or if you want to free up resources, use the wizard to remove the fire drill configuration. See Deleting the fire drill configuration. The wizard deletes the service group on the secondary site. In a Volume Replicator environment, the wizard performs a snap abort to delete the snapshot mirrors created on the secondary site for use in the fire drill. In hardware replication environments, you can delete these manually. If a fire drill has been run, the wizard ensures that you first restore the fire drill configuration to a prepared state before this option becomes available. This ensures that mirrors are reattached and the fire drill service group is offline before the configuration is deleted. |
